The Costco Member Prescription Program (CMPP) is a prescription savings program for you and your family. It allows Members who have no prescription drug insurance or whose insurance does not cover all of their prescription medication to be the beneficiaries of Costco's commitment to member service, value, quality and product confidence. Costco is committed to passing on savings to the member and are able to do that by monitoring expenses taking lower markups, and negotiating manufacturer/supplier discounts and passing those savings back to Costco members.

How It Works

To Join

Complete the enrollment form or at any participating Costco pharmacy and return it to your Costco pharmacist. There is no additional charge for Costco members to participate in the Program.

This program is NOT insurance. The program is a value added benefit of Costco membership that provides eligible Costco members and their eligible dependents the ability to obtain lower prices for certain prescriptions on the Program's Preferred Drug List.
