AMEX is offering 2X MR for a wide selection of merchants, some of them online only. These are similar to other AMEX offers, so you have to save the offer to your card before using them. The offers must be saved by 3/31/15 and used by 7/31/15. All the merchants show up on my AMEX Gold and OBC. Take a look and see for yourself if any of them are worth your while.
