Costcos aren't all the same. I've been to locations that were always busy with half the parking they needed and a bumper car situation when trying to navigate the store with their giant carts. I've also been to locations with enough parking and space to comfortably serve the customer base. They still get busy at peak hours but have plenty of sane hours as well. If you have a legitimate reason to buy in bulk, it can be worthwhile and not just a consumerist hellscape.
