CR did a report on ebaY for their August Issue. Though it obviously did not have all the right questions to ask, it did have some interesting results.
Read ebaY Report
HALF (yes that is 50%) of buyers, said they had been "deceived" by the seller in some way, from not as described to outright fraud.
40% (which gives ebaY a positive feedback rating of 60 out of 100%) said ebaY's customer service in providing help was fair (neutral) or poor (negative). Well that DEFINITELY puts ebaY in the suspended category according to their own system - much lower than the lowest 5% on their site! And that was just from buyers - can you imagine what it would have been from sellers?
