Price of the 12 Days before Chirstmas Song

It will cost your true love 6.1% more

Estimated price of '12 Days of Christmas' gift list up sharply due to gas, gold prices and bird flu.

A partridge in a pear tree will cost $104.99 this year, up 12.9 percent due largely to higher delivery costs.

NEW YORK (CNNMoney.com) - The price tag of the shopping list laid out in the classic holiday song "The Twelve Days of Christmas" is sharply higher this year, hit by such modern-day woes as higher energy and gold prices and concerns about the avian flu, according to an annual survey unveiled Monday.

PNC Advisors, which has charted the cost of the gifts laid out in the song for the last 21 years, put the price of the items this year at $18,348 in 2005, a 6.1 percent increase over last year.

Some presents will be difficult to get at any price this year. The threat of avian flu has restricted the international shipment of birds, thus preventing the purchase of three French hens from France, although there are domestic breeders of French hens which helped keep that gift's cost in line. But all the fowl mentioned in the song cost substantially more this year due to the increased delivery costs from higher energy prices.
