Quoted from PinRaider:seriously ???????
Was I saying this wrong my entire life?
No, you've probably been correct with the Economists' mantra of "Supply & Demand" but I thought this was a (probably unintentional) cool play on words, as in "I have a supply of a primo pin that's in demand". But, more traditionally, as supply decreases or demand goes up (holding the other constant), prices should rise, among other S&D effects... [apply this as you like to explain the crazy pin price explosion]
