In the mid 70s I worked for the local Providence Hammond/Steinway piano dealer in sales. The owners also owned a store in the suburbs that handled Kimball Organs and Pianos. When I left the job the had a garage loaded with traded in organs, most weren't worth the space they took up........but every once in a while someone was looking for a cheap instrument for their kids to learn on, so for $200 they may have been able to buy one from the garage. Of course, taking them to the garage was a last resort only if you were going to lose the sale. The commission on that sale wasn't worth my time either.
