I searched, but no hits… so sorry if duplicate.
I got email saying that by activating this offer I will get extra 10% bonus points through my Amazon Rewards VISA Signature Card.
Exclusive offer for select cardmembers only

Well, it is 10% on your points and some weirdly worded clause about non-eligible other promotion points, so I would not get happy…
Must activate by 30-JUN-2017. Promotion valid from 01-JUN-2017 till 31-AUG-2017.
Anyway, posting it so maybe it will work for others as well.
