The Costco or Sam's Club doesn't work for me, either. As @RadishRose says, those larger two packs of ketchup or salad dressings, will expire before I could use them in a year. Bulk buying is great for families, but large boxes of cereal, or bundles of six or large packs of fresh green peppers is a waste if the expiration date beats your usage.
Sometimes more just doesn't save you money.
