Tried to take advantage of this and have used Redbox too many times to count, tried two different types of credit cards (Visa and Mastercard), both returned an error message.
"This card not approved for games"
WTF is that?
Had this happen to me before and most recently yesterday. Rented both MHW & Fallout 4 on 9th. Returned them on 10th and rented Madden 19. Returned that yesterday and picked up MHW again. When I tried to get Fallout, it declined my card. Got the same message on my back up card.
Thought they just limited my account from renting games because in the past when my main cc was blocked, my backup would work fine. Then today I tried for Fallout again on my backup card, it went through ok. Kinda weird, but whatever it's working again
