Check your vision

But the glasses and contacts are owned by Costco, so you’ll need a membership to buy any of those. Though, you might just be tempted to sign up for one when you read these Costco shopping perks only members know about.
Pick up a prescription

Call ahead to see if your local Costco pharmacy is open to the public, then enjoy some of the cheapest prices on medication. If your store won’t let you in, you can still fill prescriptions online without paying any non-member fees.
