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.
A word of explanation on the BONUS points.
It is NOT 10% in points. It is 10% of already earned points.
Hence, if you spend $100 and earn 5% in points, that is $5, the BONUS points will be 10% of it, meaning another $0.5.
In short, instead of earning 5%, you will be earning 5.5%.
