I'm reaching out to get a quote for 300 units of a specific product I'm interested in. Could you provide me with the pricing details, including any bulk order discounts, lead times for production, and shipping costs? Additionally, it would be great to know about the available payment terms and any warranties or guarantees you offer on these units. Also, if you could let me know about the materials used and whether there are any options for customization, that would be super helpful. Looking forward to your prompt response so we can move forward with this potential order. Thanks!
