Wifi enable your garage?

Anyone done this? Seems Amazon is selling the white unit for $25 then if you have Prime, you get $30 back on first in-garage delivery.

I did with the black unit back during prime day - it was $16. I just redeemed my $30 credit (has to be on an item sold by amazon).

I just got free 3 mo prime compliments of Discover. Thinking about getting one. Thanks!
