Let's talk turkey. According to commodities researchers, Thanksgiving birds are going for record high prices this year, thanks to the rising cost of corn, the key component of a turkey's diet. "The fundamental reason why you're seeing record-high turkey prices is the fact we're seeing record-high costs of raising turkeys," says Tom Elam, a food industry and agriculture consultant based in Indiana. Here, a data-based guide to the Thanksgiving meal:

Retail price per pound of whole frozen turkey, as of September, the highest since 1980, and a 7.7 percent increase from last year

Wholesale price per pound of frozen turkey, as of last week — an all-time record, according to Russell Whitman, a commodity researcher

Price per pound for which Walmart sold turkeys last year after it slashed prices. Don't expect to see those kind of prices this year, says Elam.
