Just a gripe. I had someone, apparently a newbie, who wanted to buy a gun, even sent an FFL, but then couldn't get a grasp on sending a postal money order with a signature return receipt. I know that people get weird sending money to people they don't know, but that's how this works. Guy couldn't even get a handle on someone with over 1300 feedback rating on eBay might be honest.
Get over it or don't waste people's time.
