I am on the market for a Christmas tree and just dont know the difference between the two, neither do the people at HD or Lowes. So I thought I would ask those who know all, lol. What is the difference between a Noble Fir tree and a Frasier Fir? Why is there a ~$40 price difference for the same size tree? I am looking at 9 feet.. All help will be rewarded with karma people! Thanks!
