Not all supermarkets are created equal. For many Americans, stopping by a chain supermarket has become a major chore, involving long lines, rude employees, unsanitary conditions and poor selection.

Back in 1930, King Kullen Grocery Company in New York's Long Island became the first supermarket (though some have disputed the claim) that offered a one-stop-shopping experience for groceries. Today, Walmart is currently the largest grocer, accounting for 22 percent of American food sales in 2010, followed by Kroger, Costco and Safeway. The portion of the market taken up by the four largest grocers in the U.S. continues to increase - accounting for 37 percent of food sales in 2010, up from less than 4 percent in 1912.
