I've been doing most of my grocery shopping at Costco for more than 20 years and I still don't understand this claim. I'm only shopping for my wife and I. I have a normal sized house, normal sized pantry, normal sized car. I just don't buy things in bulk that I can't use before they spoil and I freeze all meats. Most things at Costco are barely larger than standard size. You can buy a single gallon of milk, a single quart of creamer, 18 eggs, etc. It's never once been a problem. I fill in smaller things from Aldi (like if I need a bottle of mustard). I have plenty of variety - I'm buying raw ingredients and can make a wide variety of things from them.

Shopping like you're talking about (small quantities of everything) will easily double your grocery spending, and I don't know why you would do it unless there's something about the experience you really like. If that's what you want, the chain that comes to mind is Fresh Market if you're in the eastern US, or just a local market.
