Not sure if this would be the route to take, but I'm thinking about buying myself an Amazon gift card. See, I preordered a game from Amazon, and they don't charge you until the game ships. To me, it would be a lot easier to have the money removed from my account now, so I can't inadvertently spend myself below that amount between now and then.
So I'm wondering, can I buy an Amazon gift card, input the code on my own Amazon account, and then the preorder take from that instead of my bank account? Anyone ever these and know how they work?
