Here's another reason to be grateful this Thanksgiving. According to the American Farm Bureau Federation, the average price of dinner this year will be 44 cents less than Thanksgiving 2012, largely due to a drop in the price of turkeys. A 16-pound turkey this year will cost on average $21.76, a 47-cent decline from last year. Rolls, green peas and stuffing have also seen a slide in price for this year's Turkey Day. Story.
