I'm reaching out to get some details regarding a specific product I'm interested in purchasing. I would like to know the pricing for an order of 40 pieces. It would be great if you could provide me not just with the unit price, but also any available bulk discounts or special offers that might apply for this quantity. Additionally, could you confirm the lead time for delivery, as well as any shipping options you offer to my location? It's essential for me to understand the total timeline and cost involved. If there are variations in the product or any additional features that could enhance the order, please include that info too. Looking forward to your prompt response!
