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.
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.
