There is a scam that I have been burnt with and ebay is a part of.  

We sold am item to the US from Australia, the purchaser paid surface shipping, (8 weeks), Australia Post doesn't offer tracking at this cost, buyer tells ebay hasn't been recieved, ebay givens them their money back and back charges you.  I have proof of postage, reciept & photo of item after stamps etc affixed, but ebay didn't give a rats.

eaby customer service runs from scripts and when you say something not on the script, or prove them wrong, they ignore you.

SO BE AWARE DO NOT SHIP ANYTHIG WITHOUT TRACKING NUMBER, EVEN IF YOU LOSS THE SALE

EBAY DOES NOT CARE WHAT YOUR HISTORY IS, YOU ARE IN THE WRONG
