What it is
An online shop selling trading cards, sealed boosters and boxes, single cards, sleeves, binders and deck boxes, shipped from home. You can start on marketplaces and add your own website later.
Your first three steps
- Pick one or two card games you know well and research current prices on marketplaces
- Buy a small first batch of stock plus sleeves, toploaders and packing materials
- Open a marketplace seller account, list your first 30 items with clear photos and post quickly
Who pays
Collectors, players and parents buying for children, mostly through marketplaces, social media groups and your own website.
How it makes money
You buy stock from distributors, at trade events or from collections, then sell at a margin. Singles and accessories often carry better margins than sealed products.
Skills that help
- Knowing card games and what collectors want
- Pricing singles accurately
- Careful packing and posting
- Basic photography and listing
Watch out for
- Fakes and proxies: buy from trusted sources and check authenticity before listing
- Card prices can move quickly, so avoid tying up too much money in one product
- Marketplace fees and postage costs can eat into margins, so work them out before pricing
- Check HMRC rules on registering as a sole trader and on VAT once your turnover grows
- Check whether your home insurance covers stock stored at home
