I used to just eyeball prices based on what "felt" right. Big mistake. In February 2023, I listed a vintage Patagonia Snap-T for $38. It sold on Mercari in about three minutes. I felt great until I checked eBay and realized the average selling price was actually $78. That instant loss stung enough that I had to rethink my whole strategy. After I started running items through a proper pricing tool and actually looking at the data, my average estimated margin jumped from 41% to 52% because I finally stopped underpricing my mid-tier gear.
But pricing is only half the battle; knowing which apps for selling stuff to actually use is the other half. Not all marketplaces are created equal. We’re going to break down the specific platforms that help you maximize those margins. Once the cash starts rolling in from these apps for selling stuff online, you’ll want to be smart about where it goes—maybe by using some of the best apps for budgeting to keep your side hustle finances organized. You need the right tool for the job, and we’ve tested enough of them to know which ones are actually worth the download.

The Cheat Sheet (TL;DR)
Don't Ignore the Fine Print: Always do the math on the platform's cut, shipping, and payment fees before you list. You don't want your profit eaten up by surprise charges.
Read the Room: High-end fashion belongs on Poshmark or The RealReal. A used toaster? Put that on Facebook Marketplace. Match the item to the audience.
Safety First: Meeting strangers in parking lots requires common sense. Use apps for selling stuff that offer protection, or stick to shipping-only platforms if you aren't comfortable with face-to-face deals.
Time vs. Money: Instant buy-back sites like Decluttr are fast but pay less. Peer-to-peer sites like eBay take work but pay more. Pick your poison.
Gear Up: If you're going to take this seriously, you need a phone setup that can handle constant photos, GPS navigation, and the occasional drop on the concrete.
Before You List: The Rules of the Road
It’s tempting to just download every marketplace in the App Store, but understanding the landscape of apps for selling stuff online will save you a massive headache. Not all platforms do the same thing. Some are built for speed, while others are designed to squeeze out every last dollar of profit. You need to look at the fee structure—does the platform take a 10-15% cut, or do they charge you just to list?
Also, ask yourself: are you willing to box things up and drive to the post office, or would you rather meet a stranger at a gas station for cash? Audience reach matters, too. Niche apps might get you better offers for specific things like guitars, while general apps get more eyeballs on random household junk. You also need to know the culture—does the app encourage haggling, or is the price firm?

The "Is It Worth It?" Reality Check: Imagine you find a designer blender at a yard sale for $20. You see it on eBay for $100. Awesome, right? Wait. eBay takes about 13% ($13). Shipping a heavy blender costs $25. Bubble wrap and a box cost $5. Your total cost is $20 (buy cost) + $13 (fees) + $25 (shipping) + $5 (materials) = $63. Your profit is $37, not $80. Always run these numbers before you buy inventory.
General Marketplaces for Maximum Reach
These are the heavy hitters. They are the most popular apps for selling stuff because almost everyone uses them. They're perfect if you have a "mixed bag" of inventory—some clothes, some electronics, maybe a lamp. When you use these apps for selling stuff online, you are casting the widest net possible.
1. eBay
The OG. eBay is still the king of reach. You can sell literally anything here, from broken remotes to actual cars. It is best for items that are rare or need a national audience to find the right buyer.
The Fine Print
Expect moderate to high fees, usually totaling around 13%. The reach is global, which is huge, but you have to be ready to handle the shipping logistics.
2. Facebook Marketplace
Since practically everyone has a Facebook account, this is the go-to for local sales. It integrates right into the app, so the barrier to entry is low. It's fantastic for bulky stuff like furniture that you definitely don't want to ship.
The Fine Print
You pay $0 in fees for local cash sales. If you ship items, there's a fee of around 5%. The reach is hyper-local, so your buyer pool is limited to whoever is willing to drive to you.
3. OfferUp
This is a mobile-first marketplace that’s great for local deals (it also absorbed the old letgo app). It’s built for speed, letting buyers make instant offers or message you directly. The offerup app makes the local buying process pretty smooth.
The Fine Print
Listing is free for local sales, but service fees apply if you choose to ship. It works best in cities where there are a lot of users nearby.
4. Mercari
Mercari is all about shipping, but they make it easy. They give you a printable label instantly. It is excellent for clothes, toys, and small electronics—basically anything that fits in a mailbox.
The Fine Print
Policies change often, but they recently experimented with a "0% selling fee" model where fees shift to the buyer. The reach is national within the US.
5. Craigslist
The "old reliable" of classifieds. It looks like it hasn't been updated since 1999, but it still gets traffic. It remains the best option for selling beat-up cars, scrap metal, or finding roommates.
The Fine Print
Most listings are free, with exceptions for things like cars or job postings. It's strictly local, and you should definitely be careful with meetups.
6. Nextdoor
This is the neighborhood app where people complain about loud noises, but the "For Sale & Free" section is actually solid. It has a higher trust factor because you are selling to people who live down the street.
The Fine Print
There are no fees. The reach is very limited to your immediate neighbors, so items need to be something a standard household would actually want.
Fashion and Apparel Resale Platforms
Clothes are a different beast than electronics or furniture. These apps for selling stuff online cater to people who care about fit, brand, and style.

7. Poshmark
Poshmark is a social marketplace. You have to "share" listings and engage with people. It focuses heavily on brand-name clothing and accessories.
The Fine Print
They charge a flat $2.95 for sales under $15 and 20% for sales over $15. You really need to be social on the app to get sales.
8. Depop
Think of this as a mix of Instagram and eBay. It's huge with Gen Z and focuses on streetwear and vintage Y2K styles. Aesthetics matter here; if you can take stylized photos, you’ll sell fast.
The Fine Print
Expect a 10% fee on sales. This platform is less about utility and more about the "vibe" of your shop.
9. ThredUp
This is an online consignment shop. You request a "Clean Out Kit," fill it with clothes, and mail it back. They do the work. It's the "lazy" option where you sacrifice profit for zero effort.
The Fine Print
You keep a small percentage payout. It's best for clearing space rather than maximizing income.
10. The RealReal
This is luxury consignment. They authenticate items like Gucci bags or Rolex watches. Trust is the product here, ensuring buyers feel safe spending big money.
The Fine Print
They use a tiered commission structure. This is strictly for high-end luxury goods; don't send them your Old Navy stuff.
11. Vinted
Vinted is popular for clearing out average closets filled with brands like Gap or Zara. It is great for low-cost items where paying a high fee wouldn't make sense.
The Fine Print
There are zero fees for sellers because the buyers pay a "Buyer Protection" fee. This encourages listing lower-value items.
12. Grailed
This is a curated marketplace for men’s clothing—specifically high-end fashion and streetwear. It is the place to sell that Supreme hoodie or rare sneakers.
The Fine Print
You will pay around a 9% commission plus processing fees. The audience here knows their stuff and is specific about what they want.
Tech and Electronics Marketplaces
Tech buyers care about specs and condition. These apps for selling stuff online have features to verify devices, which builds trust. You can often get instant offers from buyback sites, or wait for better offers from individual buyers.
13. Swappa
A marketplace for phones, laptops, and tablets where they verify IMEIs to prevent stolen goods. It is generally safer than eBay for phones because the buyers are tech-savvy.
The Fine Print
Seller fees are around 3%. The verification process adds a layer of trust that helps sales close faster.
14. Decluttr
You sell to the company, not a person. You scan the barcode, get an offer, and ship it for free. It is an instant sale with no waiting for a buyer.
The Fine Print
The "fee" is basically the lower offer price compared to market value. You pay for the convenience of being done with it immediately.
15. Gazelle
Similar to Decluttr, but focused specifically on smartphones and tablets. It is great for older iPhones that you just want to get rid of quickly.

The Fine Print
Fees are baked into the quote they give you. It simplifies the process significantly if you don't want to manage a listing.
16. Back Market
While primarily for professional refurbishers, they have a "Trade-in" program for individuals. It focuses on sustainability and keeping tech out of landfills.
The Fine Print
This is best for those who want to ensure their old tech is recycled or refurbished properly.
Furniture and Home Decor Apps
Shipping a sofa is a nightmare. Everyone knows it. These apps for selling stuff solve the logistics of moving heavy items or connect you with buyers looking for high-end design pieces.
17. Chairish
This platform is for vintage and high-end used furniture. It is not for IKEA furniture; think mid-century modern or antiques.
The Fine Print
Commission is around 20%. They curate the listings, so your item has to meet their aesthetic standards to even get on the site.
18. AptDeco
Specialized in buying and selling used furniture, they offer a dedicated delivery team (mostly in the Northeast and major metros). This solves the "how do I move this couch" problem.
The Fine Print
Fees vary based on the item. The delivery service is the main selling point here.
19. 1stDibs
The premier marketplace for high-end interior design and art. It is mostly for professional dealers but is accessible for individuals with extremely high-value antiques.
The Fine Print
This is an exclusive market. You need items of significant provenance or value to play in this sandbox.
Specialized Collectibles and Media
Collectors are picky. General apps for selling stuff online often lack the detailed filtering these buyers need. These specialized platforms cater to specific hobbies.
The "Condition" Difference: When selling collectibles like a Gibson guitar on Reverb or a vinyl on Discogs, condition grading is everything. If you list a guitar as "Mint" and it has a tiny scratch, you're going to get a return and a banned account. On these apps, buyers know exactly what to look for. It is better to "under-promise and over-deliver"—list it as "Very Good" and mention the scratch. You might lose $20, but you keep your reputation.
20. Discogs
The world's largest database and marketplace for vinyl records and CDs. It is the only place serious collectors look for music.
The Fine Print
They charge a 9% fee. The database integration makes listing specific pressings of records very accurate.
21. Reverb
The standard for musicians selling guitars, amps, and studio gear. Buyers here know the value of gear, so you get less low-balling than on general apps.
The Fine Print
The selling fee is around 5%. The community aspect helps in selling niche musical equipment.
22. SidelineSwap
A marketplace for new and used sporting goods like hockey, lacrosse, and skiing gear. It is great for parents whose kids outgrew their expensive gear in one season.
The Fine Print
It connects you directly with other athletes and parents who understand the cost of equipment.
23. BookScouter
An aggregator that searches dozens of buyback sites for textbooks. You enter an ISBN and see who pays the most. Essential for college students.
The Fine Print
This is a search tool rather than a direct marketplace, helping you find the best offer from various buyback companies.
Handmade and Unique Goods
If you make things or hunt for antiques, these platforms provide a storefront for your unique finds. They are distinct from general apps for selling stuff online because the buyers are specifically looking for craftsmanship.
24. Etsy
The global marketplace for handmade, vintage, and craft supplies. It requires treating your sales like a small business rather than a garage sale.
The Fine Print
You pay a listing fee of $0.20 plus a transaction fee of 6.5%. It requires some effort in SEO and shop management to get seen.
25. Ruby Lane
Strictly for antiques, vintage collectibles, and jewelry. It attracts an older, more affluent crowd than Etsy or eBay.
The Fine Print
The focus is on quality and authenticity. It is a destination for serious antique buyers.
The Physical Hustle (And Not Breaking Your Phone)
Using apps for selling stuff involves more than just tapping a screen; it involves physical hustle. Whether you are using letgo for a quick sale or fielding offers on eBay, you are constantly handling your phone to take photos, answering low-ball offers while walking the dog, and mounting your phone in the car to navigate to a meetup spot. This is where having the right gear, like Rokform, actually matters.
Photography and Staging
When you are listing 20 items on OfferUp, you need your hands free to arrange products. Rokform’s cases feature MAGMAX™ technology, which basically means you can stick your phone to a metal shelving unit, fridge, or toolbox. It turns your phone into a hands-free camera for stabilized product shots without needing a tripod. If you want to elevate your listing quality on these apps for selling stuff, check out our guide on 20 photography hacks for the iPhone to create studio-quality images that sell faster.
The Meetup Grind
Driving to meet a buyer from Facebook Marketplace requires reliable GPS. Rokform cases use a twist-lock system to secure your phone to your car’s dash or your motorcycle. Whether you are driving a truck or riding a bike to the post office, your phone stays put. If you are frequently on the road for sales, make sure you know the top 4 best places to mount a car phone holder to keep your hands on the wheel. Also, if you're treating this as a business, using mileage tracker apps can help you deduct travel expenses when tax season arrives.
Protection on the Go
Reselling involves moving boxes, loading furniture, and hustle. If you drop your phone on the pavement while loading a sold item into your trunk, a cracked screen cuts into your profits. Rokform cases are built for impact. Whether you are a casual seller or a power flipper using multiple apps for selling stuff, you need your phone to survive the process. We also recommend meeting in safe locations, but for digital safety, learn how to protect your phone from theft during face-to-face transactions.
The "Loading Zone" Save: You just sold a heavy coffee table on OfferUp. You meet the buyer, lift the table, and realize your phone is sliding out of your pocket. It hits the concrete. With a standard case, you might be looking at a $200 screen repair bill—wiping out the profit from the table you just sold. With a rugged case, you pick it up, dust it off, and pocket the cash.
Final Thoughts
Finding the right app is really about matching your item to the right audience and being honest about how much effort you want to put in. Whether you're flipping vintage tees on Depop, using legacy apps like letgo, or offloading a couch on Facebook Marketplace, the goal is the same: clear the clutter and boost your bank account.
Take a minute to cross-reference prices so you get the best offers, stay safe during transactions, and equip yourself with the right tools to make the process efficient. With the right apps for selling stuff and a solid strategy, you can turn your used goods into decent income. Good luck with the hustle.
