Me too. The only places I knew of that gave you discounted itunes cards were Costco (stopped carrying apple products) and Best Buy (I refuse to give them a dime. ONly found out by them when I was trying to find somewhere else I could get a discounted card and from what I read it was a from time to time promotion).
So, yeah, for those saying they can get a 100 dollar itunes card for 70-80, I'd love to know (and it has to not be stolen!).
We get a lot of offers on iTunes cards in the UK. This one has 33% off and other similar deals come up throughout the year.
