iTunes gift card Redemption history

No, you can't see a list of iTunes gift cards that you've redeemed onto your account

I think if enough consumer/users of iTunes brought this to Apples attention they should make a change for good business practice, where you can see all the redemption of gift cards in addition to your purchases. Similar to a checking account. Here on iTunes all you can see is your withdrawals and some balance you take to be right from Apple. #upgradeiTunesaccountinfo
