Why do so many people blame eBay for some bad sellers? There are thousands of good, genuine sellers trying to make an honest living on eBay, who will bend over backwards to help if something goes wrong just like any other company. I know this, because I'm one of them.
It's like walking down a street, picking the cheapest and dodgiest shopfront, getting ripped off by it, and then telling everyone about how evil the entire street is.
Stick to the good sellers and stick within eBay's rules and you won't get burnt.
