I'm reaching out to explore wholesale opportunities for your products. I'm particularly interested in the various pricing tiers you offer, as well as any volume discounts available. Understanding how your pricing structure works for bulk purchases will greatly help us in planning our procurement strategy. Additionally, it would be helpful to know if there are specific minimum order quantities or lead times for each pricing tier. If you have a catalog or a price list that outlines these details, I'd appreciate your share. Looking forward to your prompt response, as we are keen on forming a fruitful partnership moving forward!
