I've purchased from Cedar Valley Hunting and bought below the posted prices. Why don't you send them an offer? Doesn't hurt to try. The worst that they can say is NO and you'll wait a couple months for a cheaper one.
This has worked for me several times, at different dealers. EMT/Cash/Money Order will shave off a little bit of $. Credit Cards, even Debit (I think) costs the dealer a fee... I've received lower than posted prices with free shipping, so TRY.
Cabela's has it for $519 and $569, backordered... very little stock around. I've read that Ruger can't keep up with demand, can't build them fast enough. Good reviews, inexpensive and reliable...
Damn, now I want one!!!
