This is their great return policy...like you would ever want store credit for their horrible products:
Our return center is located in Guangzhou, China. According to our return policy, the customer is responsible for return shipping cost and any other related return charges (including possible custom fee). Your refund will be processed after our return center received and inspected the return package.
Since International return might result in long waiting time and incur substantial return cost on your side, we recommend some alternative methods to resolve this issue. We would like to offer you 15% cash refund or 20% store credit refund instead of returning the item(s). If there are any sizing issues, you can use this fund to alter the cloth.
