Microsoft teased a tie-in between Gamerscores and the Xbox Rewards system earlier this year and now they’re making good on their part by announcing rewards to players who have reached a specific amount on their Gamerscore by giving them rebates.
The Rebates work like this: Gold members with more than 25000 Achievement Points get 2% back (in Microsoft Points) on Xbox Live purchases made each month. Gold members with more than 10000 APs get a 1% rebate, while all Gold members with 3000+ APs get a “special gift” in the months of their birthdays. We do note the fine print says the gift has an approximate retail value of 25 cents.
In order to redeem these rebates you must be signed up for the Xbox Live Rewards program.
