赞比亚采购需求：数字标牌、交互式白板、工业平板电脑、自助服务终端、OLED屏幕

I'm interested in getting a quote for one unit of your smart board. Could you please provide the pricing details along with any volume discount options you may have? It would also be helpful to know the lead time for delivery and any warranty or after-sales support you offer. Additionally, I'd appreciate information on the specifications and features of the smart board. This will help me determine if it meets our needs. If you have any promotional deals or additional accessories available, please include that as well. Looking forward to your response!
