My first trip to Costco was also fairly recent.

I think I've gotten the hang of it fairly well. Coffee is over by the coolers but not in them, cat little is on the back wall, specialty cheese is near the meat, Kirland cheese is near the end of one of the coolers, cheap winter jackets are somewhere in the middle between the pants and the tortilla chips, motor oil is at the far right, bread on the left near the old people, and the big expensive life-optional stuff is at the front.

Everything else is either on the way between those points, or it doesn't exist today (because even if it is there, I'll never find it).

Seems good enough for now.
