I just logged into my Amex Blue Cash account and noticed that they’re running a sale promotion on their Reward Dollars (RD). This comes in handy to curve the overall amount of cashback you’re actually getting from the card.

Amex Reward Dollar Sale – Jan 2015

From now till Jan 15 (or while supplies last) you can get 1 of 4 gift cards for 10% fewer Reward Dollars. Redeem for a Macy’s, Barnes & Noble, Brooks Brothers or Nike gift card at $45 RD for a $50 value or $90 for a $100 value. Successfully bringing your 1% cashback to 1.1% cashback. Of course would be more if you only use it for the 3% cashback at supermarkets, but you get the idea.

You should be able to see this offer once you log into your Amex account.
