I'm looking to get a quote for 50kg of your product. Could you please provide me with the pricing details, including any bulk discount options you might offer? Additionally, I'd appreciate it if you could share information about the availability and lead time for shipment. It would also be helpful to know the payment terms and any potential shipping arrangements you can facilitate. I'm interested in establishing a reliable supply chain moving forward, so details on quality assurance and after-sales support would be great too. Thanks in advance for your assistance!
