Gamestop coupon stacking?

I wanted to get a xbox one from gamestop I have a decent amount of credit there and also about 58,000 power up points. I was wondering if the x amount coupons stack like say I got a $50 off then a $10 off one or $25 off any pre owned console on top of $50 off or use another $25 off? Any advice would be appreciated!

I was told the the console coupons will not stack with each other. You would need to talk to the manager.

Alright thanks
