Ah, yes, buying game cards, or cards that can be used for games directly might be a better plan then. At one point in time there was a reliable member here doing Amazon to BTC for a discount.

gyft.com is reliable, also I have used cryptodechange.com which was reliable, he's in the UK though, so everything denominated in UK pounds, which means you don't want an amazon or store card from there but other stuff may work. Think he does steam stuff.

Also if you do World of Tanks, or any of these http://karmakoin.com/where_to_use I've got a $10 credit in that to sell.
