A lady admiring raisins in a Supermarket The help yourself stores in America is the answer to the shopping problem. There are many advantages. Staff is cut by more than half and goods are plainly displayed for the housewife to see before she buys. On entering the store she takes a wire basket on wheels and wheeling it before her she tours the shelves on which are displayed all goods clearly marked with their prices. Her purchases completed she goes to the pay desk where the clerk reckons up the bill, takes the money and tenders an itemised receipt. 1949
