I'm reaching out to request a detailed quote for the products we discussed earlier. We're particularly interested in understanding your pricing structure, available quantities, and any potential discounts for bulk orders. It would also be great to know about your lead times and shipping arrangements to help us plan accordingly. Additionally, if there are any specific options or features available that could enhance our purchase, please include that info too. We're keen to make a decision soon, so your prompt response would be much appreciated. Looking forward to your detailed proposal!
