The 2013 Thanksgiving dinner cost according to the American Farm Bureau Federation is $49.04, lower than 2012 and 2011, but $5.57 higher than the 2010 average cost.

The average was calculated by the Farm Bureau for the 28th consecutive year. This year’s survey of 167 Farm Bureau volunteer shoppers across 34 states doesn’t account for coupons, sales or other purchase deals which could make the meal even more affordable.

The entire shopping list includes turkey, bread stuffing, sweet potatoes, rolls with butter, peas, cranberries, a relish tray of carrots and celery, pumpkin pie with whipped cream, and beverages of coffee and milk. The most expensive grocery item is the 16-pound turkey, all of the remaining items were less than $4 each.
