They check for my membership card when I come in, they check it again at the Checkout, and they check my purchases before I leave, going through the receipt and my cart.I'm not sure if there is a 10 item or less sign, I don't remember .
I'm typically a 2-4 item guy, so I would normally qualify If the sign is there.
It really doesn't save them the cost of another cashier as there are 2 or 3 people used to man the Self Check outs anyways, now maybe more.
All of them on the Front End are crossed trained, remember they also have the Cashier helper to load items as well.
I've already got to have my card out to pay, now they want it out again to confirm that I am who I say I am.
What next, check your ID before you leave the door ????
I hate Costco. They AREN'T cheaper than our local Walmart, (including the gas station) and going there to buy something is like going on a Snipe hunt. Stuff may or may NOT be there, but it's never in the same location twice.
My wife refused for me to cancel the membership though.
