Please read the following purchasing instructions and actively contact and communicate with our company. Understand and cooperate with our work. We hope to have a pleasant cooperation. We will serve you wholeheartedly and provide you with high-quality products at reasonable prices. Wish everyone a prosperous business and abundant wealth!!

Products and Prices: All the products operated by our company are "self-produced and self-sold or factory agency". The quotations published by our company online are all low-profit prices with meager profits. Please do not negotiate any further. Our company has established a network marketing center with the aim of providing a convenient one-stop procurement platform for small and medium-sized wholesalers and retailers for electrical and electronic products."

物流及快递：因为公司大多数产品属于重量性物品，大多数我们不鼓励买家走快递“因费用太高”如果真的需要，请买家咨询客服，我们会根据客户的要求来发货，，尊重客户需求。临沂的物流比较发达，所以各地一般都可以到达“不过需买家自提”，（除了太偏远地区城镇、村不能到达）。山东、安徽、江苏、浙江、上海 快递邮费较低，如买家少量采购可以考虑发快递。

Note: 1. All products sold by our company do not include shipping fees and invoices.

         2. The client company that sends the express delivery needs to collect the express delivery fee first.

         3. For customers who choose logistics, the cash on delivery method must be adopted (the customer pays the freight themselves when picking up the goods).

         4. Generally, logistics companies do not deliver to the door. Buyers need to pick up their goods at the logistics company themselves.
