Not at our Costco(s). No one gets in without checking in and no one gets out without checking out. Exception is the food window outside - though you need a Costco card to buy anything there as well. It's a pretty tight ship. It's a slight hassle but well worth the reduced prices. I've said before that Costco (and, perhaps to a lesser extent, Sams/Walmart) make living in the Islands considerably more affordable.I didn't witness the person going in the exit, but I think a person can go in for prescriptions (maybe booze) without a membership so can't scan them.
