Don't know about the states, but in Canada, you don't have to be a member to use the pharmacy, that gets you in for samples and everything.

Plus, their pharmacy is a great deal.

I think this is true in the US as well. And possibly liquor in some states (meaning a subset of the states that offer it in the first place).

This is true, but if you run into an officious gatekeeper, they will block you 'while they get the approval of the manager' before they will allow you to proceed. I hate going to Costco stores generally but their online operation is generally awesome, including prescriptions by mail.
