Is Wal-Mart taking on Tesco as the latter ramps up its USpresence? Yes, according to a report in the Financial Times. Wal-Mart is apparentlytesting four 20,000-sf, grocery-store units to compete with theBritish retailer's rollout, which will feature 10,000-sf locations.The article says that thelogo of the new store come "with a stylised tomato, egg and grapetopped by a Wal-Mart blue star" guesses that the store will "have afar stronger stress on fresh foods."We find thisinteresting because Wal-Mart already runs a grocery chain, Neighborhood Markets, which has been around since 1998 but onlyhas 128 units. Those stores average 42,000 sf. Of course, Wal-Martsells groceries at its 2,435 Supercenter locations across thecountry as well.It surprises us that Wal-Mart would consider theTesco presence a threat to its sales in the area, especiallybecause of the competition it already faces from traditionalgrocers, other discounters, specialty supermarkets, wholesale clubsand other concepts. Or is it making the best, most cautious,move?
