Well here is the problem, I wanted to buy a gamerpic on xboxlive so I found one that was 80 microsoft points. I tried to buy it but I only had 79 points. Seriously how does this happen there probably is something i can buy for 79 or maybe even 60 points but I would have to search for an hour.
So I think there shoul be an option in a new update for the xbox marketplace later on where you can buy a certain amount of points, Or maybe even an option to search up items that cost so many points. I may sound like a cheapskate but to me it sounds like a good idea.
