I'm retired BMO and unfortunately I have never had anything like this be anything other than purchase date. Sorry to tell you this but I think you may be out of luck unless you make further purchases for May.Question for those of you who are trying to meet the May targeted offer from MasterCard. Do you know if the date of purchase OR the posting date is what matters? We had a few purchases that happened on April 30th but didn't post till May 1st and without those we fall $125 short of the goal ... URGH, we really don't need anything, the car is full, grocery shopping is done, need nothing from Rexall ... it's been a pretty lean month for income so to buy something just for the sake of 160 AM is not terribly responsible
