People on both sides have unrealistic expectations.
I am selling a few bits on Ebay currently (not through my account, if anyone on here is wondering I still won't do Paypants). They're my dad's large items of furniture, as he's moving to a smaller house. Instead of dumping them, I'm listing them at £1 each, no reserve with all the proceeds going to charity.
One of the items was a piano. Someone with zero feedback sent me a message asking if I'd post it. :shock: I blocked them but now, the person who won my piano (for £1, with the proceeds to our local dogs home) isn't paying up. I'll still have to donate £1 to charity, but out of my own pocket. That can't be right, can it?
Likewise, sellers think they can sell anything. They list things that they know are no good, and do everything they can to trick people into bidding.
So, in order to be successful, everyone that uses Ebay will have to change, but they won't. I think with all these things, it's the lack of face-to-face contact that messes it up. People think they're anonymous on computers, however wrong that is it will always encourage thoughtlessness.
