I'm reaching out to get more details on the price and availability for an order of 48 units of your product. It would be great if you could provide me with your current pricing tiers, any bulk discount options, and estimated lead times for delivery. Additionally, I'd like to know if there are any minimum order quantities I should be aware of. Could you also let me know about the quality assurance processes you have in place? Understanding this will help me make a more informed decision. If there are any ongoing promotions or specific terms related to payment and shipping, please include that info as well. Looking forward to your prompt response so we can potentially move forward with this order!
