I jumped on the BTS promo and bought a new MBA and received the $100 gift card. However I'd rather have an Apple TV then a bunch of apps. In one of the BTS threads I remember seeing a post explaining how you can take money loaded on your iTunes account and somehow use it in person in an Apple Store. I tried searching but I can't find the post again. Can anyone enlighten me on this process? Or if I'm mistaken and this can't be done, can someone recommend the best place to sell a gift card?
