Speedo66 I've had an FFL tell me upon receipt of a gun I bought and paid for out of state, that since he logged it in his bound book, it was now a sale to me and I would have to pay the sales tax on it.
Needless to say, I was less than thrilled. Thankfully, he's been the only one who pulled that crap on me, and will never get the chance to do it again. Or make another dime off of me.
