I'm reaching out to explore pricing options for your product range. Could you please provide detailed pricing information, including bulk order discounts and any available shipping costs? This will help me better assess the potential for future orders. Additionally, if there are any specific terms or conditions related to the pricing, such as minimum order quantities or lead times, I'd appreciate it if you could include that as well. Looking forward to your prompt reply!
