So I see the 20% off which would make the game $48 and $10 towards your next purchase. But I don't see how you bring it down more than $48 out the door.
Edit: I'm dumb, found the $25 off Fallout 4. Guessing the 20% off first and the $25 off Fallout is suppose to stack if they allow it.
Edit...
I reserved one on my phone and went to Walmart to pick it. Then reserved another one on my phone and went to another location and picked it up. My friend did the same thing.
I just took one game back that I rented yesterday and was able to rent two more for free again... It seems like the first night is free, but there is no limit to the amount of games you can rent...
