Despite sensing the adverse impact a strong U.S. dollar and lower gasoline prices can have on its business, Costco Wholesale CorporationCOST is planning to open mores stores in the U.S. and overseas. The company's strategy to sell products at heavily discounted prices has helped it to remain on the growth track as cash-strapped customers continue to recognize Costco as a viable option for low-cost necessities. A differentiated product range enables Costco to provide an upscale shopping experience to its customers, which leads to market share gains and higher sales per square foot.
