You have to watch Wally, and Sam. They have products made to their sizes, and especially at Sam's, packaged in multiples. If you break down the cost per ounce, or per item, lot of times it's not necessarily cheaper. I was at Sam's with a friend of mine that had a restaurant. He was going to buy a 2 pack of 1 1/2 gallon Clorox, until I pointed out it was almost $1 more than 3, 1 gallon jugs at the grocery store.
