After-sales service:
We will check the goods quality before shipment. If there are some unexpected problems happen, we hope to solve the problems with buyer through friendly in the following ways:
1 If it is quality problem, buyer can submit argue within 15days after receiving the goods, buyer must provide photos or video and other evidence to seller for identify.
2 Man-made damaged, buyers take full responsibility.
3 Product quality processing program:
1) The buyer return the goods to us and responsible for return shipping costs; after we receive the goods ,we will send a new product to buyer and pay for the resend shipping cost.
2) If the goods (total price including shipping is less than 10USD) has quality problems, we will resend a new product in buyer next order; if buyer don’t plan to make a new order in the near term, buyer can pay the resend shipping cost and ask to resend a new product.
Tax:
Paying tax is the duty of every citizen, buyer need to responsible for the all of taxes. Due to the tax problem, buyer refuse to receive the goods, buyer need to responsible for freight out and home.
