I went to a sale to sell off the orchid collection of a member of a neighbor orchid society. The announcement said "Come and get some truly bargain plants while supporting a very worthy cause", the restoration of a victorian lath greenhouse in a park.
I bought the best I could find and ended up with 4 for $40. When I un-potted I found almost no live roots. I have 16 backbulb divisions. None of these will bloom for two or more years. If it had not been for the restoration contribution and the length of the drive to get there, I would not have bought any.
