Having been on the other side of the counter(where I had to answer to the owner for my buying and selling),I suspect that those that are buying the guns-and pricing/writing the ads,have no skin in the game and do not have to answer for the final profit/loss on their actions."Punch in/punch out pay day is Friday" who cares what happens in between.
The few that know guns are cherry picking the widows and divorce's prime pickings (or using a buddy to do it for them).All thats left is the over priced or ridden hard and put away wet for the customers.
