德国采购需求：喷枪、压缩机工具、气动工具、涂装设备、喷枪及迷你压缩机、配件

I'm reaching out to inquire about the pricing for an order of 20 pieces of your product. I'm interested in understanding not just the unit price, but also any bulk order discounts that might apply. Additionally, please provide information on lead times for production and shipping, as well as any potential minimum order requirements. Could you also let me know what payment options you accept and if there are any warranties or guarantees associated with this product? I'm looking to finalize this order soon, so your prompt response would be greatly appreciated. Thanks for your assistance!
