Can sellers say that they are not responsible for lost shipments when they don't have tracking information? (Registered Mail from HK)? I ask because Im considering buying a wallet from someone in HK but they say unless I use EMS that they are not responsible for lost shipments. The EMS is $50!!!!! As compared to Registered which is $10. Basically, If I choose to save $40 and use Registered and the item does not arrive, I am covered by PayPal no matter what the sellers policies are, correct? What are y'all's opinions on this?
