I'm interested in understanding the pricing structure for your wholesale products. Could you provide details on how your pricing tiers work? Specifically, I'd like to know if there are minimum order quantities, volume discounts, or any seasonal promotions that might affect pricing. Additionally, it would be helpful to get an overview of any other factors that could influence costs, such as shipping fees or payment terms. This information will assist me in making a more informed purchasing decision. Looking forward to your response!
