Query: Cheaper then through the console

Buying M$ points through Amazon is easier and cheaper then through the console. You don't have tax which is a big thing when you buy enough points over time. You get an instant code you can plug in and spend them right away. You also don't have to put a credit card on file on your Xbox, which decreases possible security issues.This is the only way I get my points anymore.
