My dad did. He found some model 94 winchesters on gunsamerica or some other such site. Sent $2500 for them, and the guns never showed up. Dad told me he got an email from the guy saying he got mugged while taking the rifles down to be shipped. Lost them as well as the $2500. I asked my dad to send me all the emails between him and the seller. Looking through them it was obvious that he'd been scammed. Just not internet savvy enough to realize it. He sent the money to an address in a town in Indiana. A search of the house showed a real estate listing for a chit box run down house with a mail box in front. They were using that address to collect the money without it going to their address. I called the local PD and got the usual "we'll look in to it" never heard anything back.
