I'm reaching out to get a better understanding of the wholesale pricing and any available discounts for the Sunday items in your catalog. We're interested in purchasing a variety of these products and would love to know more about the cost tiers based on different order quantities. Could you also provide any details about bulk purchase options and ongoing promotions that might apply? Additionally, if there are specific terms and conditions associated with these wholesale offers, it would be great to know. We're aiming to establish a long-term partnership, so insights into your pricing structure, lead times, and availability would be highly appreciated. Looking forward to your detailed response!
