美国采购需求：瓦楞塑料板盒、塑料瓦楞广告板、塑料瓦楞箱、塑料瓦楞板、塑料板

I'm reaching out to inquire about pricing for a bulk order of 4'x8' plastic corrugated boards that are 1/4" thick. We're planning to purchase a significant quantity to be shipped by tractor trailer, so I'd appreciate it if you could provide a detailed quote for this order. Additionally, if you could include any information on lead times, potential discounts for large orders, and your available payment terms, that would be really helpful. Looking forward to your prompt response so we can move forward quickly. Thanks!
