PNC - The Total Cost of the 12 Days of Christmas

http://www.pncchristmaspriceindex.com/

PNC calculates the Christmas Price Index each year as a fun, lighthearted way to look at the increasing cost of goods and services in the song, "The Twelve Days of Christmas."

This holiday season, "true loves" would pay more for all 364 items than ever before -- $75,122, up from $72,608 in 2005. This 3.5 percent increase is substantially less than last year's 9.5 percent increase.
