10 Worst Items to Buy at Warehouse Clubs

Seldom-Used Household Products

Before stocking up at warehouse clubs on household products you only need infrequently, consider the size of your home, McGrath suggests. Buying carpet/upholstery cleaner, plumbing clog remover, air freshener, and other seldom-used products, either in multi-packs or in large containers, will just take up valuable storage space underneath your kitchen or bathroom sinks, she adds.

You might even forget you stored them there and end up not using them for months at a time, if at all. For everyday shoppers, big-box retailers are the better option for purchasing these types of household products in smaller quantities, McGrath advises.
