This Thanksgiving holiday is shaping up to be a bargain, according to data from the Bureau of Labor Statistics and American Farm Bureau Federation (AFBF). The cost of food at the supermarket fell for the sixth straight month. Such prices are now down 2.3 percent from the same time last year. The AFBF reports that the average cost of a Thanksgiving meal for a family of 10 has fallen from last year, reflecting lower turkey and milk prices. The Farm Bureau says the average cost of Thanksgiving dinner for 10 is $49.87 this year, down from last year's $50.11.
