Have you ever bought a gift card to buy apps on iTunes ?
For me, I only bought an iTunes card once. The reason for this was because I used to tutor these two little boys. One of them promised to do all his homework for 7 weeks if I buy him this sac of coins for his game which costed roughly $7. I agreed to his challenge. I don't actually think he finished his homework prior to tutor time for 7 weeks straight haha aw wells. My sisters and their boyfriends use their credit cards to buy apps which works too.
I have noticed that you cannot make an apple account without putting in a gift card number or a credit card number. Correct me if I am wrong
