I'm reaching out to inquire about bulk pricing options for your products. We're looking to place a significant order, and it's important for us to understand the cost structure at larger quantities. Could you provide details on any tiered pricing, discounts, or minimum order requirements? Additionally, it would be helpful to know about lead times and any current promotions you might have. Please include shipping options and costs as well, since that will impact our final decision. We're eager to partner with your company, so your prompt response with the requested info would be appreciated!
