The best place to sell something depends far more on what it is than on which app you already have installed — a sofa, a pair of sneakers and an old iPhone belong on three different platforms. This free tool matches eleven categories of item against what matters most to you: speed, price, or not having to deal with shipping.
Sell What You Don't Use
Select what you have to sell and how you prefer to sell it. We'll suggest the best platforms and some quick tips.

How this tool works
Pick the categories you have things in
Eleven to choose from: electronics, clothing and shoes, furniture, baby and kids items, sports and outdoor gear, tools and equipment, books, video games and consoles, collectibles, appliances and a catch-all for everything else. Select as many as apply — the recommendations come back grouped by category rather than merged into one list.
Choose what matters most to you
Four options, and they genuinely change the answer: fastest sale, best price, local only with no shipping, or happy to ship. Fastest and best price rarely point at the same platform, because auction-style and specialist marketplaces reach more buyers but take longer, while local listings trade reach for same-day cash.
Read the platform recommendations
Each category returns one or two suggested platforms with a short reason — for example Swappa for phones and laptops where buyers expect working condition, Poshmark for name-brand clothing with a prepaid label included, Facebook Marketplace for furniture where buyers expect to pick up, or an in-store trade-in when instant credit beats waiting.
Use the category tips and the safety list
Every category comes with practical tips specific to it — wiping personal data from electronics, checking recalls on baby gear, listing dimensions on furniture, checking an ISBN before selling books. A separate safety section covers meeting buyers in person, which applies to every local sale regardless of category.
Price is set by what things actually sold for, not what people are asking
The single most common pricing mistake is browsing active listings. Anyone can ask any price; what matters is what buyers paid. On eBay you can filter to completed and sold listings, which gives you a real distribution rather than wishful thinking, and the same principle applies everywhere — search your item, ignore the optimistic outliers, and price near the middle of what genuinely moved. For collectibles and anything unusual, a free appraisal at a local shop before listing can stop you from giving away something with real value. Our guide to things around the house worth selling for extra cash covers which categories most reliably hold value.
Fees, shipping and the difference between the price and the payout
The number a buyer pays is not the number you receive. Marketplaces take a cut, payment processors take another, and shipping is either your cost or a deterrent to the buyer. That arithmetic decides the platform as much as the audience does: a $20 item can lose most of its value to a box and postage, which is why bundling low-value clothing or books usually beats listing them individually, and why heavy items such as furniture, appliances and larger sports gear are worth far more sold locally for cash than shipped anywhere. Consignment — dropping items at a store that sells them for you and splits the proceeds — trades a bigger cut for none of your time, which is a reasonable deal when the alternative is items sitting in a closet.
Safety, honesty and the things you should not sell at all
For local sales, meet in a public place during daylight, bring someone with you, and use the police station parking lots that many departments now designate as safe exchange zones. Take cash or a payment that has already settled in your account; be wary of anyone who wants to overpay, send a courier, or move the conversation to a different app. Photograph flaws rather than hiding them — a described scratch costs you a few dollars, an undisclosed one costs you the whole sale and your rating. And some things should not be resold: wipe and factory-reset any device and sign out of your accounts first, check the federal recall lists before selling baby gear, and never sell a car seat that has been in a crash or is past its expiration date. If you are selling to raise a specific amount, the free emergency buffer planner gives the proceeds somewhere to land.
When selling becomes a business in the eyes of the IRS
Selling your own used belongings for less than you originally paid is generally not taxable income, because there is no gain. It becomes a different question when you are buying to resell, selling collectibles for more than you paid, or operating at volume — at that point you are running a business, profit is taxable, and payment platforms may issue a Form 1099-K. Keep purchase records if you are reselling, since tax applies to the profit rather than the sale price. Thresholds have changed repeatedly in recent years, so check irs.gov for the current position rather than relying on what was true last season. If reselling is becoming regular, the free side income finder treats it as an income stream with the tax implications attached. Ask Fin is not a tax adviser and this tool is free.
How people use this
What is the best app to sell my stuff on?
There is no single best one, which is the reason this tool exists. Facebook Marketplace and OfferUp dominate local pickup and anything heavy. eBay reaches the widest audience for electronics, collectibles and specialist gear. Poshmark and Depop suit name-brand and vintage clothing. Swappa is built specifically for phones, tablets and laptops. The right answer changes with the item and with whether speed or price matters more to you.
How do I sell things fast?
List locally, price slightly under the going rate, and respond quickly. Local marketplaces remove shipping from both sides of the transaction, which is where most delay comes from. Good photographs in daylight, honest condition notes and clear dimensions cut the back-and-forth that stalls sales. Bundling similar low-value items also moves them far faster than listing each one separately.
How should I price used items?
Search for completed and sold listings rather than current asking prices, discard the unrealistic extremes, and price near the middle of what actually sold. Start a little above your true minimum so there is room to negotiate. If an item has sat for two weeks with no interest, the price is the problem, not the platform.
Is it safe to meet a buyer in person?
It is, with basic precautions. Meet in a busy public place in daylight, ideally a designated safe exchange zone — many police departments provide them in their parking lots. Bring someone with you, keep the transaction in view of other people, and for large items arrange for the buyer to come with help rather than entering your home. Take cash or a payment confirmed as settled before the item changes hands.
Do I have to pay tax on things I sell?
Selling your own used possessions for less than you paid generally produces no taxable gain. Buying to resell, selling collectibles above what you paid, or selling at volume is different — that is business income, the profit is taxable, and a payment platform may issue a Form 1099-K. Keep your purchase records if you are reselling and check irs.gov for current reporting thresholds.
Does the tool tell me what my item is worth?
No, and it deliberately does not try. Resale values vary too much by condition, model, region and season for any estimate to be reliable. What it gives you is the right marketplace for that category and a set of practical tips, plus the instruction to check sold listings yourself — which is the only pricing method that reflects real demand.
