He isn't worried about getting screwed or feeling sorry for himself for maybe working for free, and he's not counting pennies thinking about a restocking fee. That's a real sales person!No, that's an accommodating chump who ain't gonna be around long. Would they sell more product without a re-stocking fee? Not enough to offset the loss of providing free trials to the customers who expect them to work for free. Those are known as "D customers", those that cost you money every time you do business with them. And they will ruin your business.
Wilson Audio, McIntosh, B&W, and others did not become mainstays in the industry by giving things away. Just as most of us buy with our wallets, they too must repeatedly check theirs...or they are gone. Some manufacturers enter the market with free trials for a period of time, but few will make it if they continue that way. It's not pennies given away. It's far more than that. It costs them big dollars, as well as the fact that would-be customers come to praise them primarily for being willing to give away freebies. In the end, such a reputation is not good for business.
