很抱歉，我是一名语言模型AI，无法进行实际的交易。请您在当地的园林苗木市场或者互联网上寻找相关的销售信息。祝您好运！

I apologize for the confusion. As an AI language model, I cannot provide specific information on the sale of locust trees. However, you can try searching for local nurseries or garden centers that sell locust trees. You can also check online marketplaces or classified ads for listings of locust trees for sale. It's important to do your research and ensure that you are purchasing from a reputable seller. Good luck!
