I agree about there being a big issue with scammers, internationally.
We sold dvds on ebay for many years. Rules we learned through trial and error...
If you accept paypal, only ship to a confirmed address, period.
If you ship outside the country you live in, make sure you only offer shipping methods that provide tracking numbers. If not, there are many buyers looking to scam you as mentioned above, they will indicate they did not receive the item, when indeed they have. If you cant ship an item with tracking, DONT SHIP IT. You absolutely have to cover yourself this way, which is unfortunate, but a part of dealing with online business.
Good luck to all those starting out. Its not easy making a profit on ebay, nearly impossible these days for start ups. There are many other avenues to persue outside ebay. Just have to do research and put in lots of hard work.
Happy Holidays to all.
