In my perpetual state of optimism, I hoped that the part description was incorrect and that the cost for the knob was actually a cost for a set of knobs. Woe to the consumer who doubts his own eyes! Yes, you will be paying about $25 after s/h for a single knob- but it matches, it works, it fits, and it takes less than 2 seconds to install, so kudos to the manufacturer who knew this would be a good form of supplemental income from their product... I still adore Whirlpool despite their exorbitant pricing on plastic knobs... :)
