Products to Resell Online: What Sells and Where to Find It
by SOURCED Team
The best products to resell online are the ones with proven demand, a small and cheap-to-post size, and a buying price low enough to survive fees and shipping. Right now that points to sneakers, vintage and branded clothing, designer accessories, trading cards and tested electronics. What decides your profit is less the category and more how you find stock and check each item before you buy.
This guide covers what is selling, how to judge an item in a couple of minutes, where UK resellers actually source stock, and how to avoid the mistakes that eat a first budget.
TL;DR
- Categories with reliable demand include retro sneakers, vintage denim, designer bags, trading cards and electronics that you have tested.
- Before buying, check recent sold prices (not asking prices), size, condition and whether people search for the item by name or model.
- Pay roughly a third of the expected sale price or less, so fees, postage and returns still leave a real margin.
- Reliable supplier contacts save more time than endless scrolling for bargains, especially once you need repeat stock.
- Start with one category, buy a small batch, and reinvest what you learn.

What sells well online right now
Resale is no longer a side corner of retail. ThredUp’s 2026 report projects the global secondhand market reaching $393 billion by 2030, growing twice as fast as overall apparel retail. The same report says Gen Z and Millennials will drive 71% of growth through 2030, and that nearly half of shoppers find their next secondhand item through social media and creators. Those figures are largely US-based, but the direction holds for UK platforms: more buyers, and more of them arriving through social feeds.
For you as a seller, that means demand is rising, while the scarce thing is good stock. ThredUp’s report calls supply the industry’s new constraint, which is why sourcing deserves as much attention as choosing a category.
According to Quartz’s 2026 guide to what sells, the strong performers are sneakers, vintage denim, designer handbags and trading cards. Electronics move quickly too, but they punish sellers who skip testing before listing.
Sneakers and retro trainers
Quartz notes that low-profile retro styles, often called terrace trainers, are among the strongest resale sneaker categories heading into 2026. The Adidas Samba leads demand and pulls related models along with it, including the Handball Spezial, Gazelle and SL 72. These are easy to photograph, easy to size-check and sell on Vinted, eBay and Depop alike.
The catch is authenticity. Buyers expect genuine pairs, and Vinted states it has a zero-tolerance policy on non-genuine items and will block accounts that repeatedly list counterfeits. Buy from sources you can trace, and keep proof of where a pair came from.
Vintage and branded clothing
Vintage denim, workwear, sportswear and quality knitwear all find buyers, and clothing is the natural home of Vinted. Margins depend heavily on what you pay. A jacket bought in a bale or from a wholesale clearance supplier is a different proposition from one bought at full charity-shop price. Condition, label, era and size all move the final price, so photograph labels and flaws clearly.
Designer bags and accessories
Quartz reports that bags from Louis Vuitton, Chanel and Hermès often hold or exceed their original retail price, with well-kept Louis Vuitton styles routinely reselling for 60 to 80 per cent of retail. That is a strong category, but also the one where provenance matters most. Smaller accessories such as wallets, belts, sunglasses and scarves give you the same brand pull at a lower buying cost and with cheaper postage.
Electronics and games
Consumer electronics, consoles and video games sell fast. Test everything: power on, check screens, ports, batteries and software resets, and describe exactly what you tested. A seller who lists “working, tested” with photos of the screen on is far less likely to face a return.
Collectibles and niche items
Trading cards, retro gaming, fragrances, branded drinkware, plush toys and homeware from brands with a cult following all sit here. Niche products often sell at better margins because fewer sellers know where to buy them. They also move in cycles, so buy small and watch sold listings before going deeper.
How to judge a product before you buy it
A category tells you where to look. Only the individual item tells you whether to buy. A quick routine, built around HeroStuff’s reselling checklist, takes a couple of minutes:
- Check recent sold prices. Asking prices show hope; sold prices show what buyers pay. Look for a cluster of sales at similar prices, which signals steady demand.
- Confirm people search for it by name or model. If you cannot name the item in a search box, buyers probably cannot find it either.
- Check size and weight. Small, light items protect your margin because postage takes a smaller bite.
- Inspect condition. Stains, cracks, missing parts and faded prints change the price immediately.
- Work out your ceiling price. The same guide suggests paying no more than about a third of the expected sale price, so fees and shipping still leave real profit.
A worked example
Say a pair of retro trainers has recently sold for around £60 in several sold listings. Applying the one-third rule, your buying ceiling is about £20. If you can only source them for £35, the margin after postage, packaging and any platform charges is thin, and one return could wipe it out. If a supplier offers them at £18, you have room to price competitively and still earn.
The figures are illustrative, not a promise of profit. Your own sold-price checks are what count.
Know your platform costs
Fees differ by platform and change over time, so always read the current page before you price. Vinted has traditionally put its charge on the buyer through a buyer protection fee, while eBay takes a final value fee from sellers. HeroStuff cites eBay’s rise from 13.25% to 13.6% of the total sale for sales from 14 February 2025, a US figure, so check the UK seller fee page for your account type. If you want a side-by-side of the main marketplaces, our overview of secondhand selling platforms is a good place to start.
If you sell regularly, it is also worth reading HMRC’s guidance on selling online and the trading allowance, so you know where occasional selling ends and trading begins.
Where to find things to resell
Most UK resellers use a mix of sources. Each suits a different budget and time commitment.
| Source | Best for | Strength | Weak spot |
|---|---|---|---|
| Charity shops and car boot sales | Vintage, books, games, small collectibles | Very low buying prices | Time-heavy, hit and miss |
| Online marketplaces | Underpriced bargains, bundles | Search from home | Competitive, sold fast |
| Auctions and house clearances | Furniture, collectibles, bulk lots | Volume at low prices | Needs knowledge of values |
| Liquidation and wholesale lots | Bulk clothing, electronics | Scale | Mixed condition, minimum buys |
| Supplier lists | Repeat, brand-specific stock | Direct contacts, less guesswork | Needs checking per product |
The first three reward patience. They suit people with spare time and a good eye. The last two suit sellers who want repeatable stock, because you know where the next batch comes from. If you are new to the whole process, our guide on how to start reselling walks through sourcing, costs and listings in order.
Finding vintage stock
Vintage buyers search by era, brand and style: “90s Levi’s 501”, “Carhartt workwear jacket”, “Ralph Lauren knit”. Source by learning labels and fabric tags, then buy what you can describe in those terms. Specialist vintage suppliers and bale sellers can give you more consistent pieces than a random rail, but check the sample photos and the return terms before committing.
Sourcing for Vinted specifically
Vinted rewards a steady flow of listings with clear photos and honest descriptions. Because sellers pay no commission on standard sales, many people use it for clothing, trainers and accessories. Our Vinted reselling starting point explains how supplier lists fit that way of working, and the reselling guides for Vinted, eBay and Depop show how the approach shifts from one platform to the next.
Common mistakes with a first budget
- Buying too much of one thing. Order a small test batch, sell it, and then scale.
- Ignoring postage. A bulky item with cheap resale value can cost more to send than it earns.
- Skipping authenticity checks. Branded goods without a trail invite disputes and account problems.
- Chasing hype. Trends move quickly. ThredUp’s report describes Gen Z moving from high-volume hauls to hunting for “holy grail” pieces, which rewards well-chosen items over piles of random stock.
- Not tracking costs. Record purchase price, postage, packaging and any fees for every item, or you will not know your real margin.
Our perspective
Most new resellers do not fail because they chose the wrong category. They fail because they spent weeks hunting for a source they could trust, then bought on a hunch.
We built SOURCED around that problem. Each guide is a digital supplier list for resellers, with direct supplier contacts and product-specific checks, so you start from a shortlist rather than a blank search bar. The guides also cover cost calculation and the resale process on marketplaces such as Vinted, eBay and Depop, because a supplier is only useful if the numbers work once your listing is live.
Our view is simple: pick one category, use a supplier route that is built for resellers, run the sold-price check on every product, and reinvest. Speed to your first reliable source is what compounds.

A simple plan for your first month
- Week 1: pick one category and study sold listings for 20 to 30 items. Note the typical sold price and how fast items go.
- Week 2: set a budget you can afford to lose part of, and source a small batch from your chosen route.
- Week 3: photograph and list carefully. Mention condition, measurements and any flaws. Test electronics and say so.
- Week 4: record real margins, then decide what to reorder, drop or expand.
The point of the first month is data, not profit. Once you know which items sell fast at a margin you are happy with, scaling is a matter of repeat sourcing.
FAQ
What is the most profitable thing to resell?
There is no single answer, because profit depends on what you pay as much as what you sell for. Retro sneakers, vintage clothing, designer accessories, trading cards and tested electronics all have steady demand. Pick the one where you can buy at around a third of the sold price or less.
Can I resell things I buy new?
Yes, many resellers buy new or unused stock from suppliers and sell it on marketplaces. Check each platform’s rules on brand and authenticity, keep invoices, and only list items you can show are genuine. Vinted, for example, states it blocks accounts that repeatedly list counterfeit goods.
What should I resell as a complete beginner?
Start with small, light items you can describe clearly, such as trainers, branded clothing or accessories. They are cheap to post and easy to photograph. Buy a small batch first and check your sold prices before reordering.
Where can I find things to resell if I have no budget?
Begin with things you already own that you no longer use, then reinvest the proceeds into charity-shop or car boot finds. As the budget grows, move to a reliable supplier route so you are not relying on luck each week.
