The below should work too :
WJCBB-WRXS9-R35ZW-HT5TJ-9HJ59 - 1 Golden Key for Borderlands 3
5BCBB-5SRS9-RTW9C-9JCJB-XK3X9 - 5 Golden Keys for Borderlands 3 (expires today midnight I think)
Expired
Looking for 3-4 others that'd be interested in doing the raids and nightfall strikes. We even have a Clan if you're interested in joining.
