GTA 6 pre-orders went live last week, and if you haven't secured a copy yet or you'd rather not pay full price for it, Microsoft Rewards could help cover the cost.
I used the program to earn enough points to redeem Microsoft Gift Cards, letting me preorder the game without paying out of pocket. If you start now and stick with it over the next few months, you could do the same and grab the year's biggest game release without spending a dime.
