The prices for chicken seemed pretty good when we last went to Sam's Club. Unfortunately if you read the tag it says "case sell only" so the prominently displayed price was, to say the least, a little misleading. The only place the price per pound for the packages was on the packages themselves, and it was significantly higher. I wonder how many people fell for it. We almost did.
Food Lion has a better trick. Often the items in the cases and shelves for buy one get one free sales are similar to the ones actually on sale, but are not on sale at all. Not being that attentive at the checkout, I would only find this out when I got home and discovered I'd paid double what I thought I had. Now I read the upc labels on the sale items to make sure it matches the one on the sign.
I guess you make money however you can.
