Can you shop and buy for one time if you aren't a member?

By law the only thing you can go in and buy without a membership is liquor and medication. Go to the service desk and ask for a guest pass

Don't know, might be able to look

Yes, if you get a guest pass at guest services.

Is you want to get around not being able to without a membership, have a friend give you a gift card (it can be $1). You can reload it with cash. You can even use it for gas.

No
