LOS ANGELES - NOVEMBER 08: Employees teach shoppers to use self-service checkout stations at a Fresh & Easy grocery as Tesco PLC, the UK's biggest retailer, officially enters the U.S. market, opening its first six stores in southern California on November 8, 2007 in Los Angeles, California. Tesco is importing its own system of grocery store operations, making heavy use of pre-packaged produce, in contrast to U.S.-based grocery chains, to reduce overhead and refrigeration costs. The Fresh & Easy markets, which are significantly smaller than typical U.S. supermarkets, will use its own truck fleet for single deliveries from a centralized distribution center. The chain will operate from a relatively small $10,000 per square foot, producing more than a projected $200,000 a week, twice that per square foot of typical U.S. food stores.

Publix is joining the list of stores that offer self-check out lanes.
