Update! The iTunes card is sold out online! For a limited time, BestBuy.com takes an extra $10 off $50 Apple iTunes Cards dropping them to only $40. If you're an iTunes user, you should jump on this rare discount. Shipping is free and, since these are gift cards and not merchandise, there is no sales tax! For what it's worth, you can sell these on eBay for about $45! Shipping is currently "backordered" which is fine - you'll still get them, just in 1 or 2 weeks - or you can order online with the discount and select a pickup at a local store that has availability.
