I'm reaching out to inquire about the pricing and availability of the product I've referred to as P. We're looking to source this item for our upcoming project, and it would be helpful to know your current stock levels as well as any volume discounts you might offer. Additionally, if you could provide details on lead times and shipping options, that would be great! We're aiming to finalize our supplier selection soon, so a prompt response would be appreciated. Looking forward to hearing from you!
