Hey all, was going to refund a steam card I bought on game.co.uk here in the UK. They send orders under £75 untracked which this one was, the card arrived a few days ago and I'm planning to wait until next week and then tell them it didn't arrive and ask for a refund. My question is can I use the card in the meantime? Will they know that it's been used if I add it to my account and buy a game with it now? Thanks.
