If your computer can burn DVDs, you can download it through exerciseTV and burn it to a DVD. Although I guess if you don't have any blank DVDs sitting around, you'd have to go out to the store anyway, and it wouldn't actually be faster at all. But it's another option if you have trouble finding it and don't want to buy it online and wait for it.
yeah, i got mine from amazon, too. usually before buying a workout video I try to borrow it on netflix, which is a nice way to try it out before spending the $ on a purchase. happy shredding!
