One of the best ways to say a little money on the iTunes stores is to buy discounted gift cards. Today, Staples is selling the $50 iTunes gift card for $40 and the $100 iTunes gift card for $80 with free shipping. According to the product info page, the sale will last till Jan 23rd. I have known these sales to end early. If you buy anything through the iTunes stores, pick one or more of these gift cards up and enjoy a 20% discount on your next app purchase.
