At Costco, Sam's Club etc., while you have to be a member, anyone can be a member just pay the fee. So it really has always been open to the public, all you had to do was pay the huge membership fee and that other initial fee at the door as the entrance cost. Now it is just lots cheaper to get in if you only want to visit the dealers for huge bargains.
It isn't like getting into a super secret Joint Chiefs of Staff meeting!
