The member will always pay the lesser of “usual and customary” (for example, $4 for some generics at Walmart) and copay for prescriptions whether at Walmart or any retail pharmacy.

No. Members do not have to use their pharmacy benefits to get the lesser pricing for qualified prescriptions at participating discount pharmacies. Should they choose to use their Medco benefits (by showing their ID card), they will still only pay the lower price for qualified generic prescriptions and have the added advantage of Medco’s virtual pharmacy program. This program keeps track of each member’s prescription history — whether the prescription was filled through a retail pharmacy or through home delivery — and automatically checks for drug interactions. If necessary, Medco then provides the pharmacist with additional information or warnings.
