Choosing what to sell
Four checks before you buy stock to resell.
Start with stock you already understand. A card collector can judge a corner by eye and spot a fake holo; a newcomer pays for that knowledge in returns and refunds. Vintage denim, trainers and coins work the same way: knowing the stock earns you more than any kit on this site.
Then look at the size and weight of a typical sale. Cards, coins and jewellery fit a Large Letter, so postage stays low and one desk drawer holds a month of packaging. Homeware, boxed toys and camping gear go as parcels, need boxes and void fill, and take over a corner of the room. Check Royal Mail's current size guide before you price anything.
Next, think about how buyers shop for it. Collectibles sell well live, because buyers want to see the card turn under the light and bid against each other. Clothing sells on photos and search: a buyer filters by size and brand, scrolls, and decides in a minute. Choose the stock first, then the platform.
Finally, count your hours. A cheap paperback and a designer jacket take about the same time to photograph, list and pack. Low-price stock pays in volume or bundles; high-price stock pays per order but ties up your cash for longer.
Reading the cards
Each card shows how many of our setups cover that category and, where Whatnot UK has a matching browse category, how many people were watching live shows in it at the last capture. Viewers measure attention on one platform at one moment. Use them to compare categories and to pick which ones to look at closer; they don't forecast sales.
Cards and collectibles
Small, valuable and often sold live. Protection and good light come first.
Fashion and accessories
Sold on photos and sizes. You need a rail, a steady photo spot and quick drop-offs.
Home, craft and everyday
Bulkier parcels in mixed shapes. Plan for boxes, void fill and floor space.
Tech, games and media
Tested, graded and described in detail. Sturdy boxes protect your margin.
Clearance, bulk and outdoors
Job lots, house clearances and big items. Your sorting and storage set your profit.
Questions
What sells well from home in the UK?
Small, light stock with a decent price per item suits a spare room: trading cards, coins, jewellery and branded clothing. Each one fits a Large Letter or small parcel and stores in a drawer or on a rail. The Whatnot figures on this page show where live buyers are watching today.
Can I sell more than one category?
Yes. Pair your main category with a second one that shares the same packaging, such as cards with comics, or vintage clothing with handbags. Shared packaging keeps your stock of mailers small and your reorders simple.
Do I need to register as a business?
Selling unwanted things from your own home is not trading. Buying stock to resell for profit usually is, and HMRC expects you to register for Self Assessment once your trading income passes the trading allowance. Check HMRC's current guidance before your first full year.
Are some items banned from sale?
Every platform keeps its own list of prohibited and restricted items, and Royal Mail has a separate list of things you can't post, including some batteries, aerosols and perfumes. Check both lists before you buy a new kind of stock.
How do I pick packaging for my category?
Open the category page. Each one lists a packing method, the packaging we use and the usual postage service, and the packaging builder works out how much you need for your weekly orders.
