I was viewing my Amex rewards points, and noticed the following message under my account(s)
"Take 15% off Membership Rewards points needed to pay off eligible November Shop Small charges on your statement by 31 January 2015"
That is 1000 points = $8.24 , a very good convertion.
To redeem the points, go to "membership rewards", and choose "select + Pay with points". Please note some Amex accounts might not have this redeem option.
Velocity cards won't, as the points are (instantly?) transferred to velocity rewards.
AMEX Platinum Edge should, but for some reason that card never receives the promos in account management (probably because the Velocity card does?). Thus I didn't use it for Shop Small this period.
