I hope you can provide me with a detailed quotation for the products we discussed earlier. It would be great if you could include your pricing, minimum order quantities, and any relevant bulk order discounts. Additionally, I'm interested in understanding the lead time for production and shipping, as that will help me plan our inventory more effectively. If you have any current promotions or package deals, please share that info as well. I'm looking for a comprehensive breakdown so that I can assess the potential for a long-term partnership. Your prompt response would be greatly appreciated, as I'm eager to move forward with this procurement process. Thank you.
