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 interested in exploring your wholesale pricing options for products available in the United States. Could you provide a detailed breakdown of your pricing structure, including any volume discounts or tiered pricing that you offer? Understanding these options will help us determine the best fit for our purchasing needs. Additionally, it would be great if you could share information about minimum order quantities and shipping costs associated with wholesale orders. This information is crucial for us to evaluate our potential partnership. Looking forward to your prompt response!
