Ebay is offering a Four pack of $15 iTunes gift cards for only $55. That’s 8% off the list price and shipped to you for free. We’ve seen higher discounts before, but this arrives just in time for Father’s Day or Graduation. You can redeem and use the iTunes gifts on the iTunes Store, App Store, iBookstore, and Mac App Store. There’s no credit card required. All they need is a free iTunes account, and they can immediately use their gift credit for whatever they want — songs, movies, TV shows, books, apps, and more.
