Really sucks how GMG treat pre order customers and their lack of price protection like Amazon and other stores offer.
"oh you pre ordered the game a while back and the price is now cheaper? Sorry, we can't refund you the difference or offer to even cancel the order."
Now they ended the coupon early (even though it was meant to last longer) and are denying pre orders the difference.
Definitely 20CUPHEAD was a mistake.
I got my refund from GMG and was able to use the voucher just 10 minutes ago, and got it for 12$. Can confirm that 20CUPHEAD doesn't work anymore.
This is some bullshit,
I got this email earlier then that, when I asked for a refund if they couldn't give me the difference in price:
"Thank you for getting in touch with us. Unfortunately this promotion ended earlier that anticipated and this title is no longer compatible with vouchers. I apologise if this causes any inconvenience. "
Of course, the coupon DID still work at the time (this was like 3:00), but they didn't refund me (even though I asked) so I couldn't place a new order and even try it.
