Sebastian Mallaby in the Washington Post:

According to a paper for the National Bureau of Economic Research by Jerry Hausman and Ephraim Leibtag, neither of whom received funding from Wal-Mart, big-box stores led by Wal-Mart reduce families' food bills by one-fourth. Because Wal-Mart's price-cutting also has a big impact on the non-food stuff it peddles, it saves U.S. consumers upward of $200 billion a year, making it a larger booster of family welfare than the federal government's $33 billion food-stamp program.
