Questions in regards to a Facebook account?

I don't buy jack diddly doo doo from marketplace unless it's someone local and they are in facebook group in common to me. Then normally, the item is for sale on that group page. I'm not gonna buy from someone not local, so that helps reign in some of the possible scams. Now if it's somebody on my friend's list, or someone I know from here that might be different. But I'm not getting myself into a position where I might lose money with no recourse such as using a pay service that has no buyer protection (think Paypal). I know lots hate Paypal, but I've had precious few deals go wrong using it and gotten my money back every single time, without fail. You can say it's a ripoff all you want (I agree for our Canadian friends), but why do you think they're in business? To stroke your ego with almost or free transactions? Hardly.
