I hope this message finds you well. I'm reaching out to gather more detailed information regarding your pricing and shipping options for a recent inquiry. Specifically, I am interested in understanding not just the unit costs but also any volume discounts you might offer. Additionally, it would be helpful to know if there are any extra fees we should be aware of, such as shipping costs or handling charges that could affect the overall pricing. Furthermore, I'd like to get a clearer picture of your shipping timelines. Could you please provide estimated delivery times for various order quantities? If possible, information on shipping methods and any potential delays during peak seasons would also be appreciated. This will help us in planning our inventory and ensuring we meet our deadlines effectively. Thanks in advance for the detailed insights!
