I'm reaching out to gather detailed information about your FOB pricing and any wholesale gradient pricing structures for bulk orders. We're in the planning stages of a significant procurement and it's crucial for us to understand the pricing tiers clearly to optimize our budget accordingly. Additionally, if there are any volume discounts or special terms for large orders that we should consider, please include that information as well. We're looking to establish a reliable partnership, so insight into delivery timelines and payment terms would also be beneficial. Looking forward to your comprehensive response to help us move forward.
