iTunes Billing Question

[Devils'Advocate]

Okay. I have a US iTunes account. I set it up using the Vanilla Mastercard method. Plus a friend sent me a $100 iTunes gift card.

I stupidly redeemed the gift card before using the balance on the Vanilla Mastercard.

I currently have a $50 balance on the Mastercard which is now dwindling $2.50 per month in "service charges". And I have $50 left on the iTunes gift card balance. I have about $50 of purchases that I want to make. However, by default, iTunes takes from your gift card balance first and your credit card balance second.

Is there any means of changing that?

Never mind.. I figured it out.

If you purchase iTunes gift cards, it charges ONLY your credit card. So I purchased a $50 gift card on iTunes, emptying the Vanilla Mastercard, and bumping my iTunes store balance to $100.
