I have Discover Benefit card every time I charge any Rx copayment they pay it then for proof that I paid eligible items. It is really getting bad it now every credit card transaction is challenged by the company. I never had this problem for the years their codes match at the time of purchase in Walmart pharmacy I was never asked to produce any proof of purchase eligible items. I am so frustrated with the process I think next year when my money in account exhausted I will stop putting money in this account. It not worth the headache and it has a very small deduction anyway. it is nightmare experice dealing with this company.
