When you walk in, just let them know you aren't a member, but you want to buy a gift card for a member. They will bring you to customer service (and talk to you about purchasing your own membership), and you can get your gift card. Just remember- the ONLY charge they accept is VISA. If you don't have a Visa, make sure you have cash to cover the card.
You can't even get though the door, without a membership card. When you get to the door, they send you to customer service, there you can get a gift card.
