I remember a number years back Yamaha offered all their retail accounts a very good price for all old organs they could take in part exchange so this would generate new organ sales.
Many dealers on an arrange day took old organs to Yamaha who then crushed them again a wall with a tractor, this arrangement carried on for a few months until the dealers with their vans waiting in a queue started to buy these old organs off each other. So Yamaha stopped what could have been a successful idea.
