There's three doors in, from left to right, exit, entrance and liquor. The leftmost is where customer service is. You can sign up there or if there are tents from grand-opening.
You can sign up in store or purchase a membership online. Just make sure to have valid photo ID. Since this Costco just recently opened, there are tents set up outside also to help with setting up memberships.
Just walk up to customer service and tell them that want to be a member. They'll have you fill out paperwork and then you'll pay the fee. That's pretty much it if memory serves.
Yes they have a tent setup outside the warehouse to sign up at.
Take a valid photo ID into Costco with you. Takes about 5 minutes to sign up.
Walk in the return side and walk up to the counter, takes about 5 mins.
