If you go to Costco, wear blinders! My biggest problem is coming out of there for under $200. It's even worse if hubby is with me. I get to the checkout and find all sorts of things I would never have bought if I had been alone.
LOL...that is true....the food may be cheaper....but the actual trip will quite likely cost you a lot (you mean you DIDN'T want a 4 litre jar of olives or a box of 50 chocolate bars?)!
