I had used the coupons.com app a few times but it had been a month or so that there was anything I used. Finally I bought 2 packages of M&Ms at CVS and submitted a copy of the receipt for reimbursement. I never got a confirmation receipt so I tried again, but got a notice that I had already submitted it. It's been three weeks and no rebate. I tried to contact the help line on the app but never got any clear answer what to do. They claim they never got it but I can't resend it. There is no phone number to call and no email to write to. I never would have bought the product if not for the rebate.
