美国采购需求：微量营养素肥料、蟑螂胶饵、植物生长激素、家用杀虫剂、农用化学品、公共卫生杀虫剂

I'm interested in getting a clearer idea of the price range for your products. Could you provide me with the starting cost? It would be great to understand what factors might influence the price, such as quantity, specifications, and any available customization options. I'm looking to make informed decisions for future orders based on this information. Additionally, if there are any discounts for bulk purchases or special promotions currently available, I'd appreciate details on that as well. A breakdown of costs associated with shipping or handling would also be helpful, as I want to factor those into my overall budget. Looking forward to your response!
