美国采购需求：货运三轮车、机动三轮车

I'm interested in the model mentioned in my previous inquiry. Can you please provide me with the pricing for a single unit? This will help me assess my budget and determine how many I might want to order. Additionally, if possible, could you share details about any available bulk purchasing options or discounts? Understanding your shipping terms and lead times would also be beneficial for planning. Looking forward to your prompt response!
