US Pixel 2 promotion works overseas

Not sure if it's a bug on Google's end, but I was able to redeem the code I received for purchasing a Pixel 2 in the US Google Store for a free Google Home Mini in the Japanese Google Store.

The promotion fineprint said it is only available for those in the US and must be redeemed in the US store, so I was surprised to see this worked-- I was about to give me code away!

The Home Mini retails for 6,500 yen here, so big savings compared to the current $29 in the US.
