I'm reaching out to inquire about the wholesale pricing for your products. We are interested in purchasing a significant quantity and would like to understand the price per unit based on bulk orders. Additionally, if you could provide information on any discounts available for larger purchases and your minimum order requirements, it would be greatly appreciated. We're looking to establish a long-term partnership and your prompt response will help us evaluate our options. Thanks!
