Study Shows Euro Lead

London, APlanet Retail study says that, despite being some of the fastest-growing retail businesses in the United States, grocery discounters and dollar stores have a long way to go before they match the penetration of their counterparts in Europe. Discount retailers in the United States control only 1.7% of the U.S. retail market, while those in France control 6% and in Germany 30%, the study said. The top five leading domestic discount chains—identified by Planet Retail as Dollar General, Family Dollar, Save-a-Lot, Aldi and Dollar Tree—will not collectively account for 5% of the U.S. retail market until 2020, Planet Retail said.
