The way I've heard the story before, was that Kildall was surprised when he finally saw the price sheet for the pricing of CP/M-86 vs PC-DOS. I guess we can either interpret that as he priced it too high and had no idea what MS were charging for PC-DOS, or that IBM deliberately priced them out of the market.
