We have a local chain of about ten stores that now has an online gun list, and while the webmaster is posting the guns on their site, the good ones get grabbed by walk-in customers. I suspect the same thing happens with Cabela's. Those stores get a lot of traffic, and good stuff will go quickly if it's priced right.

With Guns International, I suspect dealers put up some guns just to draw calls, even if the gun has already been spoken for but not yet transferred. Then they leave the guns up for way too long.
