Anecdata: I am the administrator of a ~12k person "Free & For Sale" FB group for the college that I graduated from. It's very high traffic, people are able to buy and sell a whole host of things very easily.
I think Facebook has the potential to combine eBay and Craigslist as a platform to sell more "common" items. They won't be able to get your broken laser pointer to a broken laser pointer collector, but if you want to get rid of a bed/desk/cell phone/microwave, it's much easier to sell it to someone that lives 10 minutes away than to ship it across the country, and the risk of fraud is much lower.
I know they have plans to scale this out and improve the experience of buying and selling things (I've been messaged by a few FB staff asking for feedback as they've added new features), but it definitely does not have the critical mass that CL has, and discovery (getting into the right group) is much harder.
