Real Christmas trees can range in price depending on the type of tree and its size. Generally, a 6-7 foot tree can cost anywhere from $40 to $100, while a 7-8 foot tree can cost anywhere from $60 to $120. The price can go up from there for larger trees or for trees with special features such as being pre-lit or having decorations already added. Prices can also vary depending on where you live and what time of year it is. It's best to check with local retailers to get the most accurate pricing information.
