Unless you get stevestojan lucky on the scratch-offs, I don't think there's any way you could win 900(?) donuts that's equivalent to if you buy $52 worth from the store or preferably Gil whenever there's a discount (day-old donuts, Christmas donuts, etc.).
As I said, I put some down from an iTunes gift card I got over the holidays. I mean... I don't really buy music on this (YouTube and actual CDs for me, mostly). I've gotten a few books and a couple of apps, but my iPad is basically a portable Internet/camera/music/old-school-gaming device. I don't mind plinking down from a gift card, but actual dollars that come from my pocket? Ehhh.....
