墨西哥采购需求：活性药物成分、发酵产品、食品添加剂、原材料

I'm interested in your products and would like to know more about your pricing details. Could you provide me with a breakdown of costs for bulk orders? It would also be helpful to understand any discounts you might offer based on quantity. Additionally, please share your shipping options to Mexico. I'd like to know about the estimated delivery times and any associated fees. If you have different shipping methods, I'd appreciate insights on those too. Thanks!
