美国采购需求：工业计算机制造商，坚固型计算机制造商

I'm reaching out to inquire about pricing for bulk orders. We are based in the United States and are interested in placing a significant order for your products. It would be great to understand your pricing tiers based on different quantities, as well as any discounts available for larger purchases. Additionally, could you provide information on lead times for delivery and any shipping costs to our location? Understanding these factors will help us make an informed decision and potentially establish a long-term partnership. Looking forward to your prompt response!
