I don't know
From Costco's FAQ online: Costco's pharmacies are open to non-members where required by state law. The Costco Member Prescription Program is a value added benefit of a Costco membership. However, you do not have to become a Costco member or join CMPP to continue buying prescriptions at the pharmacy. ...best to call the pharmacy directly and ask them since this policy is ruled by state law.
Sure you can. It's a state law. No membership required
