So I bought the Xbox One version, and it says it's delayed till 12/31, but also in my email it says PC download even though it says X1 version below it.
On the old system yes it will go through sometimes, but on the new updated ones that we just got recently in my store, no it won't. At all.
It's such a mess now, we have to use hashtags to preorder games and stuff. I hate it so much.
It's not a "rule", I work at Gamestop and even if you enter 2 coupons it will do only 1 99% of the time and you'll just lose the other code for nothing.
But if you get a nice enough employee, like me ;), then we would return the most expensive B2G1 item and then use the other coupon on that.
