I don't think so you have to show membership card at door.
You cannot buy with out a member ship
Tell them you want a membership as you come in and they will direct you to a desk where they explain the membership. After that, they will ask you if you want to look around before you purchase a membership. But you cannot make a purchase without it. It is well worth the membership.
You can probably find someone who will bring you in as a guest. Or you can tell them you're thinking about getting a membership and probably just walk in.
No. You must have a membership to enter Costco or shop with a member. However, membership is fully refundable.
