You can buy discounted wineglasses by purchasing them from discount and factory outlet stores, by shopping for them online, and by purchasing them in bulk through restaurant supply stores. Discount stores such as Big Lots and Christmas Tree Shops often carry wine glasses at substantially reduced prices.
Glassware manufacturers such as Libbey and Mikasa often have discount stores located in factory outlet malls that sell discontinued items and open stock wineglasses at prices below retail. Sites such as Overstock.com and Amazon.com also carry wineglasses at discounted prices and Amazon often has deals on bulk quantities. Restaurant supply stores may also carry wine glasses at discounted prices. Some may require bulk purchases, but many of these stores sell smaller sets of four to six glasses.
