I was browsing the Xbox live marketplace when I spied the deals of the week and they were all 3 Borderlands DLC for 400 MS points each! I was about to buy them when I realized my little brother used most of my points on the MW 2 Resurgence pack. I only had enough for General Knox and Zombie island. So I was wondering if you can buy a DLC download code like you can with the Fallout 3 DLC? I don't want to buy a full points card just for 400 points (800 when the sale ends).
