Costco Pharmacy is open to members and non-members, but its pitch is aimed at members, who get member-only prescription pricing they can check online before transferring. Refills can come by mail, or be delivered the same day with groceries through Instacart, and select warehouses add Rx locker pickup and Pay Ahead for faster collection. Costco says it accepts most major insurance plans and that people without coverage still get competitive pricing, and its registers take Medicare Advantage OTC benefits, FSA and HSA cards. Members can book $29 virtual appointments with doctors through Sesame for new prescriptions or refills without insurance, and the same account handles pet medications and immunization bookings. We could not confirm a USD price from our location, so its price is marked pending. Value depends on whether you already pay for a membership; for occasional prescriptions alone, a no-fee option such as Cost Plus Drugs may cost less.
