We do our best to help you get an item, contact a seller, make a payment and ship an item to you safely. However, we are not liable for the damage of the item, improper representation and any other fraudulent activities. So please place a bid with self-responsibility.

If a seller has low feedback score or some negative feedback, we recommend you to stay away from them. Even if you haplessly fall victim to a fraud, you are responsible for all of the payment.
