I force nearly all of my first time transactions through LocalBitcoins, even though it costs me 1% (which tends to be a decent percentage of the profits), and if the buyer/seller refuses to transact through Local bitcoins for at least one ("get to know you") transaction, then I refuse to do business with them... hahahahaha.... it's my way of making sure that I get folks who are ready, willing and able to comply with all of the terms of my ad.. rather than to either attempt to negotiate new terms or otherwise be difficult to deal with (which sometimes can be the case in meeting random folks through the interwebs).
