I've bought a total of three guns over the internet; kept them all. I did negotiate the price on one of them after receipt due to a difference of opinion on condition; the seller agreed. The other two went off without a hitch. Frankly, it never occurred to me that "three day inspection period" meant anything other than just that: within the three days, I could return it for any reason, even if I just changed my mind. I'm glad I didn't find out the hard way. Of course I was willing to pay shipping both way, and the FFL expense would be on me; that's my part of the risk involved. The risk to the seller is that I might return it, and he loses a sale.

One thing this thread has done for me: I'll be damned sure of the "conditions" of the return policy, should I ever do it again.
