A&P Sold $1 Billion of Groceries From 16,000 Stores. The Government Convicted It for Pricing Too Low.

The Great Atlantic & Pacific Tea Company ran a one-word strategy, volume, and by 1929 it was the first retailer in history to sell $1 billion in a year, from nearly 16,000 stores and 70 factories. Its crime, a federal judge ruled in 1946, was using that scale to keep prices too low. Congress had already passed a law to stop it.

In 1859 George Gilman opened a tea-and-coffee shop on Vesey Street in lower Manhattan and named it, grandly, the Great American Tea Company. A decade later, rechristening the firm for the newly finished transcontinental railroad, the Great Atlantic & Pacific Tea Company set out to do for groceries what the rails did for freight. For fifty years it was a respectable but unremarkable chain. The decision that made it the largest retailer in the world came in 1912, from John A. Hartford, the salesman brother, over the objections of George L. Hartford, the cautious brother who kept the books.

John's idea was the Economy Store: a tiny shop capitalized at $3,000, staffed by a single manager, with no telephone, no credit, no delivery, a short list of fast-selling goods, and a target gross margin of 12 percent instead of the usual twenty-something. Every cost the old corner grocer carried, the Economy Store dropped, and it dropped the price to match. The prototype hit $800 in weekly sales and a 30 percent annual return. A&P opened one, then two, then three a day. By 1920 it had 4,638 stores; by 1929, nearly 16,000.

The mechanism was one word: volume. Low prices drew shoppers; shoppers gave A&P purchasing power no wholesaler could match. The Hartfords spent it on vertical integration, building 70 factories and more than 100 warehouses, becoming the country's largest coffee importer and butter buyer and its second-largest baker. They refused to buy through wholesalers and demanded suppliers pay A&P the commission a wholesaler would have taken. Every saving went back into the price. "We would rather sell 200 pounds of butter at 1 cent profit than 100 pounds at 2 cents profit," John Hartford testified. In 1929 A&P became the first retailer ever to sell $1 billion of goods in a single year, more than twice the next largest retailer, Sears, and it priced its goods 10 to 15 percent below the typical independent store.

This was a flywheel, and like all flywheels it had enemies. The hundreds of thousands of mom-and-pop grocers, wholesalers, and small canneries it undersold could not beat A&P on price, so they beat it on politics. In the 1920s a working-class family spent a third of its budget on groceries, more than on housing, and the food trade employed one in eighteen non-farm workers; the people A&P was rendering inefficient were a constituency. State after state taxed stores by the chain. Then, on June 19, 1936, came the Robinson-Patman Act: suppliers could no longer sell more cheaply to a big buyer than a small one unless they could prove, case by case, that the big order genuinely cost less to fill. Wright Patman, the Texas congressman who drove it through, said restricting the chains would keep "Hitler's methods" out of American business. The average publicly traded grocery chain lost 58 percent of its market value between the bill's introduction in June 1935 and December 1937, while the Dow rose 8 percent.

The criminal case followed. On September 21, 1946, in a courtroom on the second floor of the Danville, Illinois post office, Judge Walter C. Lindley convicted George Hartford, 81, John Hartford, 74, their company, and other executives of conspiring to violate the Sherman Act. The crime was not charging too much. A government lawyer called the world's largest retailer "a gigantic blood sucker," but the victims were not shoppers; A&P's prices were below its competitors'. The victims were the competitors. Lindley conceded that selling "one and three-quarter billion dollars worth of food annually, at a profit of one and one-half cents on each dollar, is an achievement one may well be proud of," and ruled it illegal anyway: "The Sherman Act was intended to secure equality of opportunity." Each defendant was fined $10,000. A&P's national grocery share had already fallen from 11.3 percent in 1933 to 7.1 percent in 1943, even as the government insisted it was becoming a monopoly.

The restraints melted away in the 1950s as the political wind turned. By 1962, when Wal-Mart, Target, and Kmart opened their first stores, selling cheaply was legal again. A&P, run by less capable managers after the Hartfords died and taken public in 1957, never recovered its nerve; it filed for bankruptcy in 2015 and closed its last store. Wal-Mart, working the same volume-and-vertical-integration playbook A&P had invented half a century earlier, became the largest company on earth, unbothered by the Robinson-Patman Act that had been written to bury its predecessor.

The takeaway. A&P's binding constraint was never cost or scale; it was political legitimacy. The most efficient distribution machine in the country lost to a coalition of inefficient competitors who wrote the rules, because the people it displaced, grocers, wholesalers, small canneries, were a visible constituency and the shoppers it served were not. When you displace an entrenched layer, expect the fight to move from the market to the legislature, because that is the one court where efficiency is not a defense. Wal-Mart won the same fight a generation later only because, by then, cheap food had become politically untouchable and the displaced were fewer. Build the machine, but bankroll the politics. Antitrust broke AT&T in 1984 for the opposite sin, using a monopoly to overcharge; it convicted A&P for charging too little. It is a tool, and whoever holds it decides which direction it cuts.
