If you know what you want, I would say check a few local shops to see what they have in stock and then if they don't ask them if they can order it. So far the only shop that I have dealt with recently that is still in business is Baltimore's Best Pawn, they have been great to deal with.
Most of the IP's here, (Industry Partner's section), post the transfer fees and show the discount on that fee to mdshooter members. I'll even go so far as to give you the link: http://www.mdshooters.com/forumdisplay.php?f=106
