Costco is an interesting one to me. They're widely touted as being cheaper, but most foods there have some sort of upscaling factor -- "organic", some sort of regional variation like "sockeye" salmon instead of farmed atlantic, a few extra steps of processing, etc. Rice, pasta, and fruit are all usually more expensive than other alternatives, even at bigco grocery competitors. You have to be a little careful if that's where you do all your shopping.
