Received this offer in the mail for Discover cashback bonus card. Pretty good offer for straight cashback. This translates to 2.78%. This is on top of the regular 1% cash back.

I rarely use this card. Used this recently for a big purchase for 5% shopdiscover bonus. I guess this offer was triggered by that.

Below is the text of the offer.
