1. check his feedback first sometimes seller just kind of easy and lazy. 2. feedback如果不好那麼先寫信問他如果三到五天內沒有回信那麼到Paypal file the claim within 3 days you will get the full refund (<usd 2000)from PayPal. 有些賣家生意做的很大根本不回信 東西自然會送到東西岸Ground mail約12天左右所以等待是難免的
How to file a claim with PayPal: log-in paypal then go to "Resolution Center" follow the step by step there then within 7 days you will get the answer/refund from PayPal.
Just make sure the seller DID NOT MAIL out your item yet otherwise it's very "ugly" after you filed the claim!
