That’s a pretty steep discount! However it’s not live yet on the Google Store and apparently it’s limited to the US market for now.

EDIT: even at this time the deal is still not live on Google Store, looks like they might have a supply problem.
On Google Fi however it is listed but it is out of stock:
EDIT 2: looks like Google canceled the deal.
I really miss having a dedicated fingerprint reader on the rear.
