我无法提供实时的商品价格信息。建议您在当地的花卉市场或者在线花卉商店进行查询。

I apologize for the confusion. As an AI language model, I do not have access to real-time pricing information for specific products. However, you can try searching for prices of red maple trees in the United States on gardening websites or online marketplaces. Prices may vary depending on the size, age, and location of the tree. It's also a good idea to check with local nurseries or garden centers for availability and pricing.
