Well, any shop has expenses to pay and they may get deep discounts on currently-available products, so don't get upset at any offer. We used to buy guns all day at 40-50% of real-world, walk-in selling value. I recall a customer who came back a month later thinking we should sell "his" gun back at the same price we paid him for it. Hmmm...
If you can get to 19th St. and Camelback, Legendary Guns has done me right on more than a few deals both ways. Further south, Guns Etc on Alma School or the Pistol Parlor are all I'd recommend. Most of the really good shops on the north/NE side are gone. Now most of them all look the same and are run by big money investors, so BL/SH rules the day. Drive to Prescott and we'll discuss in detail!
Personally, I'd insist you list them here on the Classifieds, and boxes are free at FedEx... remember you can ship directly to any AZ resident, no FFL required unless you so choose. That makes shipping in-state very advantageous to the buyer!
