GAME is now selling Steam Wallet codes, and is the first retailer in the UK to offer the codes at retail, the company announced today on its official Twitter account.

The codes are available in sums of £5, £10, £15 and £20, and can be used to add one-time credit to a Steam account. Until Dec. 7, buyers will also receive a 33 percent discount on codes when putting trade-in credit towards the purchase. All trade-ins used toward code purchases will also earn buyers extra GAME Rewards points.

Like select GameStop stores in the U.S., 200 GAME shops will keep tablets on the floor allowing customers to browse the entire Steam PC catalogue.

GameStop began selling Steam Wallet codes at retail back in May.
