It's Costco. They have everything you need and everything you don't. Lines we're quite, despite store being packed. It WAS Saturday afternoon, so I went in knowing this would be my experience.

Couldn’t find the big bag of quinoa. Asked an employee stocking shelves, she walked me right to it. Saved me circling the aisles.
