eBay feedback is eBay specific. But the recent feedback policies attract and encourage some people be a "difficult buyers" to try to get more than they paid.

eBay is a big flea market in real, the difference is that there is a "customer feedbak board" behined every sellers.

How to avoid to get a bad seller lable from the difficutly buyers?

I study my market competitor's store, but I got no ideas on how they can selling 1/3 or 1/4 costs low quality products at similar price of mine, but no troubles from their buyers?!

Ripping off 90% unknown buyers to satisfy 10% difficult buyers in 45 days buyer protection period? After that, buyers can do nothing, because the Fair Trading do not accept complain online private seller's case?

And I found those difficult buyers are "very smart buyers", they always come back to my store again by use other eBay IDs. Although I try to push them to there. They don't waste time and money to the lower quality products seller!

Nothing serious, just shopping and selling on eBay for fun.
