PayPal’s official eBay storefront offers a $50 iTunes gift card for $40 with email delivery (20% savings). Use this discounted iTunes credit to save on apps, music, movies, books, and more. Outside of few rare occasions, this is about the best deal you’ll find on iTunes gift cards.
Gift cards will be emailed so you’ll be able to start downloading discounted iTunes media sooner rather than later: “In most cases, this will be within a few hours of purchase. However, in some cases it may take up to 24 hours.”
