Best Buy offers a iTunes $100 Digital Delivery Gift Card for $100. In-cart, it falls to $80. Although we saw it for $60 earlier today, since expired, it's still $20 off and a very good price for iTunes credit. (It's essentially 20% off.) Sales tax is added where applicable. The gift card code will be sent by email and can be redeemed for music, movies, TV shows, audiobooks, apps, and more.
