Real Christmas trees can vary in price, depending on the size, type, and where you buy them from. A small tree can cost as little as $10 to $20, while a larger tree can cost upwards of $100. Trees sold at specialty nurseries or Christmas tree farms tend to be higher quality and more expensive, while those bought at supermarkets or department stores may be more affordable. Additionally, pre-lit or artificial trees can be more expensive than fresh-cut trees. However, it's important to remember that the cost of a Christmas tree is a small investment in the joy and tradition of the holiday season.
