How i get the most out of it when i Buy MSP

This is how I get the most stuff out of it when I buy MSP.
1) I use GameStop power up rewards. (PowerUp Rewards - Home Page) (I have pro)
2) When ever i get MSP i buy it from gamestop with my power up account. (http://www.gamestop.com/xbox-360/acc...box-360-live-m...) (So after a while you can redeem you power up points to get cool little toys from games or posters. cupons, etc.)
3) I signed up for Xbox LIVE Rewards and then when ever I get MSP and spend it you get a % back at the end of the month. (you have to be geting atleast 100 msp back to get it but it also builds up from month to month)

This may not be much, but if you get alot of msp you may just get a little more out of it
