I'm interested in placing a significant bulk order and would like to get more detailed information regarding your pricing structure for large quantities. Specifically, I'd appreciate it if you could provide the pricing tiers, any available discounts, and minimum order quantities for shipment to the United States. It's important for us to understand the lead times as well, so any info on production and delivery timelines would be very helpful. Additionally, it would be great if you could share details regarding payment terms, warranty policies, and any special offers or promotions that might apply to bulk orders. We are looking for a long-term partnership, so understanding these aspects will assist us in making an informed decision. Looking forward to your prompt response!
