南非采购需求：有氧运动器材、空中自行车、商用跑步机、家用椭圆机、直立自行车、踏步机

I'm reaching out to get more info on your plate-loaded bicep curl machines. I'm particularly interested in understanding the pricing details for a quality option that can meet the demands of a commercial gym setting. Could you provide a breakdown of the pricing, including any minimum order quantities or discounts for bulk purchases? Additionally, I would like to know about the specifications, warranty options, and lead times for delivery. If there are any promotional offers or new models available, please include that as well. It would be great to have a comprehensive overview so I can make an informed decision for our gym's equipment needs. Looking forward to your prompt response!
