If your Christmas isn't complete without a real Christmas tree, then you should probably be ready for some sticker shock. A nationwide shortage of trees means a higher price for the centerpiece holiday decoration in your home.

A longtime Christmas tree retailer says they have had to explain the higher Christmas tree prices to a few customers. The reason for the shortage is is slow sales in 2007. Because of the slow sales, the National Christmas Tree Association says farmers didn't plant as many trees. That slowdown in planting means there are not enough trees of the size needed this year.

One customer told KTSM that she didn't mind the higher price because she had grown up with fake trees. When she began buying her own, she started buying real Christmas trees.

I have a fake Christmas tree because several family members are allergic to real ones. I wish I could put up a real tree, so cheers to those of you who can!
