Facebook Marketplace - An Ebay Killer?

I sold my first item last night through Facebook Marketplace, my iMac G5. I would have most likely listed it on Ebay if Adam hadn't suggested listing it on Facebook first. The market place itself is a lot simpler than Ebay and has no security or buyer/seller protection but it is free.

Recently I've become more frustrated with high Ebay fees, in general 10% of the total cost of the item goes to Ebay in some way through listing fees, final value fees and PayPal fees. This would be close to £50 for my iMac. Facebook Marketplace offered an alternative that was free so I had nothing to lose by listing my item.

It was about a week before someone contacted me for some more information about my iMac which I was happy to provide. We bartered a little and he decided to come pick it up and pay cash (it was his first Mac as well). I will admit this is not normally how Ebay works and could be down to the testament of Facebook's perceived value of being a friendlier (safer?) place.

The transaction went smoothly, he had my iMac and I had money towards a new one. I'm not sure how good Facebook would be for other items - are people really searching there for mobile phone chargers or antiques yet? Perhaps this is all still to come, Facebook's demographics are in its favour as well, with the average user being better educated and earning more than users from other social networking sites such as Myspace and Bebo.

As for an Ebay killer well its too early to tell, but as I've seen over the past week the process certainly works. Has anyone else sold items on Facebook Marketplace or might give it a try after reading this? Any bad experiences?
