The price of live Christmas trees varies depending on the size, species, and location. Generally speaking, smaller trees can be as low as $15-20, while larger trees can cost upwards of $75 or more. In some cases, you may be able to find a better deal if you purchase from a local nursery or farm. Additionally, the price may also depend on whether you're buying a cut tree or a live tree that can be replanted after the holidays. It's always a good idea to do some research and compare prices before making a purchase.
