I'm interested in trying out your product and would like to purchase a box for evaluation. Before finalizing the order, I was hoping you could provide me with a special discount on the price. I believe that a favorable price would not only encourage me to proceed with this initial purchase but may also lead to larger orders in the future if the product meets my expectations. Looking forward to your response!
