I'm reaching out to inquire about the wholesale price for your products. I've been reviewing your offerings and I'm interested in understanding the pricing structure for bulk orders. Could you provide details on the cost per unit at various quantities? Additionally, if there are any discounts available for larger orders or specific terms of sale, I would appreciate that info too. It would also be great to know about any current promotions or special conditions that might apply to new customers. Understanding shipping and lead times is crucial as well, as I'm planning to assess our inventory needs. Looking forward to your prompt response so we can potentially move forward with an order.
