text:  The cost of living actually fell slightly between May and June as a drop in gasoline prices more than outweighed the modest monthly rise in rents. Grocery prices rose just a tenth of a percent during the month, while restaurant prices rose four-tenths. Airfares and new and used car prices were down in June. Scott Horsley, NPR News, Washington.
