Since I am an app buying addict (don't keep track of how much I'm spending, etc.) I'm thinking I just need to buy myself an itunes giftcard every month to limit what I buy. In the itunes store you can buy itunes email certs, since it doesn't say itunes music, can I assume I can also use it in the app store? I could just go to the store and buy one, but this would be way more convenient.
iTunes Gift Card = iTunes credits which are good for anything. Still, if you can just get them online, it doesn't really give you that mental restriction, because you can just as easily get another one. If you stick with a physical card, everytime you run out of cash, you realize you have to go to a store and physically part with your money, which makes it easy to hold back on your expenses.
Good point, but at least I'll have to take one extra step other than just click "buy" I took my credit card info out of my itunes account. We'll see how that goes.
