Years ago I bought the Freddie Redd set used and the booklet was missing. I emailed Mosaic, told them what I had done and offered to buy a booklet. They sold it to me for $10, no questions asked.
When the Mobley set came out, I had all the CDs (TOCJ or US) and did not want to buy the set. I told them exactly that and asked if I could buy the book. Again, $10, no questions asked. Probably helped that I have been a loyal customer since 1985, but these guys/gals act like family - it is amazing.
