It was just a suggestion since that is a large price difference.
It is a lot harder for the salesman to discount now or they may be reluctant because if you have a certain percentage it comes directly out of your pay. In this business, that has to be one of the stupidest policies I have ever heard. They may have changed this since I went back to school but it was dumb as hell.
So, I guess although the company would rather have your business sometimes it will actually hurt the person selling you those tires, ya know what I mean?
