Better yet, sell the barrels for $200 and have a "standard" installation fee of $36, $50 or whatever should cover it and shipping. That way, Rockport, or any other customer, can look up the price of a barrel and install/shipping price if they decide they want Savage to do that also. Rockport (and other customers) would know exactly what the costs are without having to tie up a sales/service person from the company and Savage would probably be able to increase work productivity with less phone calls working up the chain of command to supervisors.
Odds are, they would draw more business, both for the barrels and for installs and for a much improved customer service. Americans are kind of funny about stuff like this--WE like doing repeat business with a company that we can trust and that takes care of us by valuing us as customers. Maybe some of the other manufacturers should consider this also. (Uhh, Remlin, cough, cough, cough).
