STEVENS, Pa., Aug. 30 (UPI) -- It's not surprising Mitt and Ann Romney enjoy shopping at Costco, because it is the only discount retailer that attracts the affluent, a U.S. expert says.
Pamela Danziger, president of Unity Marketing and luxury market expert, said Costco was the only discount chain that attracted more ultra-affluent -- consumers with more than $250,000 income a year -- than lower-income shoppers, with income ranging from $100,000 to $249,900 a year.
