南非采购需求：OEM SD 卡，批量购买 SD 卡，SD 卡最优价格，SD 卡批发，定制 SD 卡，原厂 SD 卡

I'm interested in obtaining wholesale pricing for motherboards, as I'm looking to bulk purchase for an upcoming project. It would be great if you could provide details on your available models, their specifications, and any minimum order quantity requirements you might have. Additionally, if you have a catalog or a list of your products with pricing tiers based on order volume, that would be super helpful. I'm also curious about any potential discounts for larger orders or if there are special promotions running. Looking forward to your prompt response so we can explore potential collaboration opportunities!
