Want to buy from iTunes but don't want to use your credit card? No problem. Just head on over to a pharmacy, supermarket, big box, or any of the myriad of places that sell iTunes gift cards, buy one for yourself, and use it to top off your account. (Extra tip: Costco sometimes has packages for a few dollars off, like $50 worth of cards for $45).
The tip comes by way Ian Ross and Shelby Lee Engels, who shared it with Apple's iTunes team.
