This may be YMMV, but please check your checkout page when ordering through Amazon.com. You may see a $90 reward, which typically is $30 for a new Amazon VISA Rewards card application (from what I have seen so far).
Good thing with this CC is that there is no spending requirement. You get the credit instantly.

FYI: I am a Amazon Prime member and was placing an order of around $40.
I am new when posting deals, so please be kind
