Costco is how I fed my teenage boys without going broke. You do have to know your prices and just keep that in the back of your head. The in house brands for food are terrific quality.

I don't do much produce there, but I do get: fresh pastas, coffee beans, 6-8 packs of various canned good, specialty items like real paremsean cheese and sundried tomatoes, meats which I portion up and freeze, boxes of luna bars... I also get a lot supplements. The eye care at our local costco is excellent.

They had the best price on a CR Best Buy rated lawnmower that we wanted.

Note on flooring- this is one item I would be very careful about. We've done about 3000 ft-sq of hardwood laminate, and my professional installer friend who gave us tip warned us off of it, it's not that great.
