Definitely makes sense to get the best deal you can. Congratulations caj and BWG on your new R/T's!
I would not call a dealer a crook for selling at MSRP. Back when Challengers were (sometimes) selling at markup, many of us acted like there was some sort of moral imperative to sell at MSRP. Now that some dealers offer a discount from MSRP, the guys offering MSRP are suddenly money-grubbers?
Now this does NOT excuse the rude treatment that caj received from his salesman. That salesman lost business, and rightfully so with his attitude. If he was not willing to lower his price, he should have said so firmly and politely, and left it at that. No-haggle pricing can be effective, and even refreshing to deal with, but trying to guilt-trip, browbeat, or trick a customer into paying more is not acceptable.
