Never tried to sell a gun online, but 2 years back I listed my jeep on a local buy/sell site. I got a text,( I didn't give out my home phone #), from a guy who wanted to buy it. He was gonna send a truck to get it. I told him fine as long as the Money Order cleared the bank. He sent me a text after the m/o had arrived and I reminded him that it had to clear. I didn't try to cash it, but deposited it. I didn't like the fact that the m/o was for about $1,000 more than I was asking and I was supposed to give the extra to the truck driver to pay him. I looked up the area code from the texts and it was from around the Miami Fla area. But the m/o was bad so I kept the Jeep. I have a friend in real estate that told me that anything, check, money order, certified check, etc. can all be printed off from your home computer. As for PayPal, my wife had to use that one year to pay her RN license renewal fee here in Arkansas. A week later while she was at work, I got a call from someone who just barely spoke English claiming that there was a problem with her account. He claimed to be from the Health department. I asked him what state? Instead of Arkansas, he mispronounced the abbreviation AR as Hay horra! I told him that his number was on caller id, and when my wife got off work she'd call, and hung up. So I don't use PayPal.
