Affiliate disclosure

Last updated 16 September 2026.

The short version

Some links on this site may earn us a small commission if you buy something. It never costs you anything extra, and it never changes the prices we show you or the order products appear in.

How the numbers are produced

The prices on this site come from two places:

• Shop price — the cheapest price we have found the sealed product at, from a real UK retailer. We collect these by hand and check them again as new shops list stock.
  
  We deliberately do not call this "RRP". There often isn't a single recommended price: the same mini tin sells for £8.99 in one shop and £9.99 in another, and The Pokémon Company does not publish a UK price list to us. Quoting one number as though it were official would make every markup percentage on this site slightly wrong.
  
  Using the cheapest shop price means the markup we show is the most conservative honest figure. If anything, we understate how much extra a reseller is asking. Where we have not yet confirmed a price ourselves, the product page says so.
• eBay prices — pulled automatically once a day from the eBay UK marketplace. These are asking prices on listings that are currently for sale. They are not sold prices, and they are not what an item is "worth". A seller can ask any price they like.

We take the cheapest handful of listings that survive our filters and average them, so that one silly listing cannot swing the headline number. We filter out single cards, multi-item lots, pre-orders, empty and opened boxes, code cards, non-English products and suspiciously cheap listings that are likely to be fakes. The filtering is not perfect. If you spot a listing that should have been excluded, please tell us.

What we are not

SealedCheck is not affiliated with, endorsed by, sponsored by or associated with The Pokémon Company International, Nintendo, Game Freak, Creatures Inc., or eBay Inc. We use no official logos, card artwork or product photography. All trademarks belong to their owners.

This is not financial advice

Trading cards are not an investment product. Prices can fall as easily as they rise. Nothing on this site is a recommendation to buy or sell anything. Please make your own decisions.

Getting it wrong

We may make mistakes. Prices change between our daily update and the moment you look. Always check the actual price on the retailer's or seller's own page before you pay. If you find an error, email hello@sealedcheck.co.uk and we will fix it.
