Is there any way to have an iTunes account without entering any credit card information?

Personaly, I hate giving out information like a CC# unless it is a place I intend to frequently shop. Too much room for error or theft that way. With that in mind, I suggest purchasing a $25.00 Gift Visa and use about $15 off of it. Then you should be able to use it for things like this. Maybe not, but it's worth a try since your financial risk is so low.
