I'm interested in exploring the pricing options for your block machinery. Could you please provide me with detailed information on the various models available? It would be helpful to know the features, production capacity, and any additional costs associated with the machinery, including shipping and handling fees. Additionally, if you have any promotional offers or discounts for bulk purchases, please include that info as well. Understanding the warranty terms and after-sales support would also be beneficial. Looking forward to your prompt response so we can move forward with this potential partnership.
