I received my promo email for my free google home mini.
I followed all of the steps to link my account and even reached the check out page. At this point, it showed correctly as $0. I realized I chose the wrong color and hit the back button on my phone’s browser. Now whenever I try to redeem, I am being prompted to pay $49 and have no option to redeem my promo option.
I contacted Google Support and they didn’t have an answer.
