My credit card is offering me a $5 statement credit if I spend at least $5 on iTunes. Problem is I have a large credit balance - how can I get iTunes to charge my credit card instead of using up my apple credit?
If you have a balance on your iTunes account then that will automatically be used for purchases before your credit card will be - you can't change how items are billed.
You could try gifting items to yourself, you can only gift via a credit card (I haven't tried it but I think that you should be able to gift items to yourself)
