I'm reaching out to inquire about pricing for your products. We are interested in understanding the cost for bulk orders and any possible discounts for larger quantities. Additionally, it would be helpful to know the lead time for delivery once an order is placed. Could you also provide details on the minimum order quantity and any shipping options available? This information will assist us in making a more informed decision as we look to establish a long-term partnership with your factory. Thanks in advance for your prompt response!
