Apparently this is a good offer to buy some gift card, I tried and hotels.com, uber, play, safeway etc, gift cards will trigger the promo.
However, since I have not use my amazon account for a while, when I tried to use this offer, amazon shut my entire account down for 2 hours and cancelled my order.
Amazon, do better, and don't be a **bleep**.
Wasn't able to either. Boo.
