I apologize for the confusion. As an AI language model, I cannot provide real-time sales information for specific locations. However, I can provide some general information about purchasing fast-growing willow trees.

If you are interested in purchasing fast-growing willow trees, you can search for local nurseries or garden centers that specialize in selling trees and plants. You can also search online for willow tree suppliers or visit websites that sell trees and plants.

When purchasing fast-growing willow trees, it is important to consider the specific variety of willow tree that you want to buy, as well as the size and age of the tree. You should also consider the climate and soil conditions in your area to ensure that the tree will thrive in your location.

Additionally, you may want to consider purchasing willow tree cuttings or saplings, which can be planted and grown into mature trees over time. These can often be purchased from nurseries or online suppliers.

I hope this information is helpful. If you have any further questions, please feel free to ask.
