I'm reaching out to request a quote for a total of 120 units of your product. I'm particularly interested in understanding the pricing structure, including any bulk order discounts you might offer. Additionally, please provide information on lead times for delivery, as well as the available payment options. It would also be great to know about any warranty or after-sales support included with the order. If you have different variants or specifications of the product, I'd appreciate it if you could outline those as well. Looking forward to your detailed response so we can proceed efficiently!
