eBay is a great place for scammers to get free stuff!
every few years, my girlfriend gives eBay another chance and tries selling something. Every single time, she gets scammed. Each time, the buyer claims he didn't receive the goods or received the wrong thing. eBay automatically sides with the buyer and immediately refunds their money. In cases where the buyer claims they received the wrong thing, they either fail to return it or return something different.
Furthermore, sellers cannot give negative feedback to buyers so there is no concept of buyer reputation. On top of this, you will still be charged for the listing.
I've used eBay to buy and sell furniture locally with some success. This is, however, a very small niche that is starting to be better served by http://gumtree.com.au here.
Basically never use ebay.
