I spoke with Bob Baker on this subject this afternoon. He said they sell only to and thru licensed FFL dealers. What each dealer charges is strictly up to the dealer. He said if you get 5% to 10% off MSRP that's a pretty good discount from most dealers. More will likely be cuz you and him are good buddies.
As to how long it takes I guess I dunno. Kinda depends I suppose. Don't think it took more than 2-3 weeks on mine if I recall correctly but don't hold me to it. And it was over the holidays so that delayed it a bit. Dunno if it being a writer review sample got it here faster or not.
