Costco is optimized to sell you stuff in large quantities each time you visit the store. They explicitly trade convenience (i.e., you can't buy a single roll of paper towels there) for extremely low prices. If you want a store that offers a nicer, more convenient shopping experience (along with significantly higher prices), there are plenty of alternatives available to you.
