4 Things to Buy in Bulk—and 3 to Buy in Small Quantities

Morgan, who checks the prices at Costco about once a month, says deodorant and other personal-care items can actually be more expensive when you buy them in bulk. You're much better off at the grocery store or drugstore, since these retailers often discount health and beauty products to get customers into the store. And while most warehouse clubs don't allow manufacturers' coupons, supermarkets and drugstores absolutely do. By using one (look for them on the manufacturer's Facebook page), or even two (you can usually also add a store coupon), you just might walk out of the store with a practically free stick of deodorant or tube of toothpaste.
