This promotion is only available for Mother’s Day weekend (May 7-8, 2011) and only by calling Discover Card and having it added to your account. I had this promotion added to both my wife and my Discover Miles cards today, but there is a chance it could be applicable for other Discover cards as well. This promotion is only available by asking and is not listed on your account when signing in.

Call 1-800-DISCOVER, get to the rewards menu, and get an agent on the line. Ask them to add the Mother’s Day promotion to your card.

I was informed that the promotion is for unlimited double miles on all purchases this weekend only and is only available on request.
