for what it is worth i might as well go to work tomorrow and knock up a couple of "Great Garage Scheme" signs on the number plate machine and screw them on the wall, they would probably have as much effect as joining any of the many product tied schemes that are about today, ie none. I get my customers by the quality and value of my work, nothing more nothing less, you know if you have it right by looking at your diary not how much space you have on the wall
