Each code gives 5 golden keys:
Expires 25th of May
Actual link to redeem: https://shift.gearboxsoftware.com/rewards
Isn't that the same link I posted in OP?
In the description yes, but not as the deal link. That just goes to the account page.
Nope, the one you posted in the description is to to "home" with a url parameter to redirect to the rewards page. Tapping it on my phone just takes me to the account page (home) and doesn't redirect.
I think I fixed it now :) Thanks!
