Having just ordered a pack from Amazon, I can't argue that Amazon isn't the better deal for me.
No tax and free shipping make the Amazon deal pretty sweet. However, if I would have known about this deal, I probably wouldn't have ordered from Amazon because I wanted some media today and not in a few days. (Projected delivery is a week from now, but my burner wasn't supposed to arrive for a week and it was here the next day.)
So, for speed, this deal wins and you can pay cash at Office Depot, in case you don't want to put any more stuff on your credit card. I didn't want to put any more on my card, but you gotta do what you gotta do for media.
Still, I'll probably head out to Office Depot and check this sale out...thanks for the info.
