Reselling is one of the most accessible ways to make money online. No startup capital required for a test run, no technical skills needed, and the market is already there — eBay alone has over 130 million active buyers. Getting started is genuinely easy. Doing it well takes a bit more thought. Here's what actually matters.

What Reselling Actually Is

Reselling means buying items cheaply and selling them at a higher price, or selling things you already own that you no longer need. These two approaches look different in practice:

Selling your own stuff — clearing out clothing, electronics, books, and furniture you no longer want. Zero upfront cost. The ceiling is limited by what you have, but it's the right way to learn platform mechanics before putting money into inventory.

Sourcing to resell — buying at thrift stores, garage sales, estate sales, retail clearance, or wholesale with the intention of selling at a profit. This is where reselling becomes a business rather than a decluttering project.

Most people start with their own stuff, make some sales, see how the process works, and then start sourcing once they understand what moves.

What Actually Sells

New sellers often list whatever they have on hand and wonder why nothing moves. Some items sell well online; others sit indefinitely. Knowing the difference before you list saves time and frustration.

Some categories move reliably across most platforms:

• Branded clothing and shoes — Nike, Lululemon, Patagonia, Free People, Coach, and similar names move quickly. Generic or unbranded clothing is much harder to sell.
• Electronics — phones, tablets, laptops, game consoles, headphones. Even broken electronics sell for parts on eBay.
• Video games — games, consoles, controllers, accessories. Retro games in particular have a dedicated and price-insensitive buyer base.
• Collectibles — Pokémon cards, LEGO sets, Funko Pops, vintage toys, sports cards. Research current market values before buying — these fluctuate more than most categories.
• Home goods — KitchenAid, Vitamix, Le Creuset, cast iron, Dyson vacuums. Quality kitchen and home brands hold value well.
• Vintage items — vintage clothing, furniture, décor, and kitchenware have dedicated buyers willing to pay for the right pieces.

What's harder to sell:

• Unbranded clothing without notable features
• Books (low margins, very competitive)
• Large furniture (shipping costs erase most or all of the margin)
• Cheap seasonal décor
• Anything you can't photograph clearly

Before sourcing an item to resell, search completed and sold listings for that exact item on eBay. Sold listings show you what buyers actually paid — not what sellers are asking, which is often disconnected from reality. This is the most reliable free research tool available.

Which Platform to Start On

The most common beginner question is which platform to use first. The honest answer depends on what you're selling.

Start with eBay if you're selling electronics, video games, collectibles, tools, or anything with a broad buyer base. eBay has more active buyers than any other resale platform and supports every product category. Fees are more complex than some platforms but buyer volume compensates. See our eBay selling guide to get started.

Start with Mercari if you want the simplest possible experience. A flat 10% fee, no listing fees, and a clean interface make it forgiving for first-time sellers. The buyer base is smaller than eBay but the learning curve is lower. Good for getting your footing before worrying about platform strategy.

Start with Poshmark if you're selling clothing, shoes, or accessories. Poshmark's buyers are specifically fashion-focused, which means your items surface to the right people. The 20% commission is high, but shipping is handled for you with a flat-rate prepaid label, so there's less to manage. See our Poshmark selling guide.

Start with Depop if you have vintage clothing, streetwear, or Y2K pieces. Depop's buyer base skews younger and specifically seeks those categories. Its fees are the lowest of any major platform — roughly 3.3% + $0.45 per sale — which makes it well-suited for lower-priced items where Poshmark's flat fee would eat too much of the margin. See our Depop selling guide.

Start with Etsy if you're selling handmade items, vintage goods, or craft supplies. Etsy's buyers actively seek those categories and will pay more for them than buyers on general marketplaces. See our Etsy guide for resellers.

You don't have to pick one and stay there forever. Once you're comfortable with how listings work, cross-listing the same item across two or three platforms takes a few extra minutes per item and meaningfully increases how fast things sell. See our guide on selling across multiple platforms.

Before You Create Your First Account

Two things are worth doing before you sign up anywhere.

Pick a username that works across all the platforms you might ever sell on. Your username is your brand. A buyer who has a great experience with you on Poshmark might search for the same name on eBay — if they find you, that's a repeat customer. If they don't, that trust doesn't transfer.

Check that your preferred username is available across all the reselling platforms before you commit to it. This takes about 30 seconds. Realizing a year and 400 reviews later that your name doesn't match across platforms is a headache that's hard to fix. For guidance on picking a good name, see our guide to choosing a username for your reselling brand.

Understand each platform's username rules. Every platform has different character limits and restrictions — eBay allows 8–64 characters, Poshmark requires 6–15, Etsy shop names have their own separate rules. See username rules for every reselling platform before you decide. A name you love might not be valid on one of the platforms you're targeting.

Once you've settled on a username and verified it works everywhere, creating the accounts themselves takes 5–15 minutes per platform. See our step-by-step account setup guide for each one.

How to Price Items

Pricing is where new sellers lose the most money — usually by underpricing because they're anxious to make their first sale.

Look at sold listings, not active listings. Searching for an item on eBay shows you hundreds of active listings — but those are just asking prices, and many of them will never sell. Filter for completed and sold listings to see what buyers actually paid. That's your real ceiling.

Work backward from fees. Decide what you need to keep, then build up from there:

Then add your cost of the item on top of the target sale price.

Price with room to negotiate. On Poshmark especially, buyers routinely offer 20–30% below listed price. If $40 is your actual target, list at $50 and plan to accept around $42. Pricing with no buffer means either leaving money on the table or declining offers and watching the item sit.

Use sold listings to set your floor. If you see 30 items listed at $20 and the sold listings show things clearing at $12, you need to price at $12. Being the cheapest item that actually sells beats being the second-cheapest item that never moves.

For a more detailed breakdown by platform, see our pricing guide for resellers.

Writing a listing that sells

The difference between a listing that sells in two days and one that sits for two months usually comes down to photos, title, and description.

Photos. Use natural light and a plain background — a white wall or neutral floor works. Show the item from multiple angles. Photograph every flaw: a stain, a scratch, a loose thread. Buyers who see flaws in photos don't complain; buyers who discover flaws they weren't shown file returns and leave bad reviews. Most platforms allow 4–12 photos per listing. Use them.

Title. Use all the characters available. Include: brand name, item type, key descriptors (color, size, model number), condition. "Nike Air Max 90 Men's Running Shoes Size 10 White/Black EUC" beats "nike shoes" because buyers search for specifics. Your title needs to match what buyers type.

Description. Answer the questions a buyer would ask before messaging you: exact measurements, what's included, what flaws exist, where it was purchased, any relevant history. The more complete your description, the fewer messages you get, and the more confidence buyers have to purchase without back-and-forth.

Shipping Basics

Weigh and measure before listing. Carrier rates depend on both actual weight and dimensional weight (a rate applied to large, light packages). Miscalculating — and getting hit with a $6 surcharge on a $20 sale — kills your margin fast. Get a postal scale and measure every package before you list.

Stock supplies before your first sale. Boxes in a few sizes, bubble wrap, packing tape, and a scale. Running to find a box after you've made a sale is stressful, and it makes you slow to ship. USPS delivers free Priority Mail boxes and envelopes to your door if you order online.

Ship fast. Most platforms expect shipping within 1–3 business days. Buyers rate you on speed. Shipping in 24 hours leads to good reviews; shipping on day 3 leads to messages asking where the package is. Treat your buyers' orders the way you'd want your own handled.

Print labels without leaving the house. Stamps.com lets you buy discounted USPS and UPS postage and print labels from home, then schedule a free carrier pickup instead of standing in line. New accounts get a 30-day free trial, $10 in free postage per month for three months, free mailing supplies, and a free digital scale.

Common Beginner Mistakes

Listing too many items too fast. New accounts have no reviews. Buyers who don't know you will look at your feedback before buying. Start with 5–10 items, make some sales, build trust, then scale. A smaller, active store with reviews outperforms a large new store with none.

Ignoring what the market is actually doing. If there are 40 identical items listed below your price, yours won't sell. Check comparable sold listings when items sit for more than two to three weeks, and reprice accordingly.

Not tracking costs. Seeing money come in feels like profit. But actual profit per item is: sale price minus platform fees, minus what you paid for the item, minus shipping, minus packaging. This usually comes out to 20–35% less than the gross sale. Track each item's cost and net so you know what's actually working. Once you're consistently profitable, it's worth reading whether you need an LLC to protect yourself.

Cross-listing without a system for unlisting. If the same item is listed on eBay and Poshmark and it sells on eBay, you need to remove the Poshmark listing immediately. Missing this means selling the same item twice — one buyer won't receive their order, you'll get a cancellation on your record, and the dispute is time-consuming to resolve. Set a daily habit of checking for cross-listing conflicts whenever you make a sale. See our multi-platform selling guide for how to manage this at scale.

Racing to the bottom on price. A clear, well-photographed listing with a complete description consistently outsells a blurry listing with a vague title, even at a higher price. Quality of presentation matters. Invest in good listing habits before cutting prices.

Getting That First Sale

The first sale is the hardest because you have no reviews and buyers don't know you yet.

A few things that reliably help:

Price slightly below market for your first handful of sales. If similar items are selling for $35, list at $30. Your goal at the start is reviews, not maximum margin. Once you have a few positive transactions, raise prices to market rate.

Respond to messages fast. Platforms show your response time on your profile. Fast responses signal reliability and convert inquiries into sales.

Engage with the platform's tools. On Poshmark, sharing your listings regularly puts them in front of active buyers. On Mercari, sending offers to people who've liked your listings converts browsers into buyers better than any other tactic. On Depop, following potential buyers increases visibility. Each platform rewards sellers who use its built-in features.

Start with what you know. If you have experience with electronics, start there. You'll write better descriptions, answer buyer questions more confidently, and recognize good sourcing opportunities faster. Expertise in a category is a real advantage.

Before you create the accounts

The first step is picking and checking your username. Run it through Username Inspector to confirm it's available on eBay, Poshmark, Mercari, Depop, Etsy, and the other platforms you're targeting — all at once, in a few seconds.
