埃及采购需求：门窗五金、窗插销、门把手、窗铰链、闭门器、窗锁

I'm looking to get a better understanding of your pricing for some products I'm interested in. Could you provide me with a detailed quote? It would be great if you could break down the costs and any bulk discounts available. Additionally, if you have any special promotions or terms for new customers, I'd love to hear about those too. Quick response would be appreciated as I'm trying to finalize my purchasing decisions soon. Thanks!
