I've taken over our household budget from DH and trying to find ways to both save money and time. Warehouse shopping never appealed to me, but I don't know anything about it except most people I know love Costco. Do you really save a lot of money by shopping there? Can it be a substitute for, say, Target? In other words, can I get all the major brands at Costco for beauty/care products and household items in addition to groceries. What about baby supplies?
