Supply and demand.
Folks hear that there is going to be a price jump, so they stockpile, creating more demand while the supply stays the same. And magically the price goes up. I wonder why that is?
Now, now , be gentle. My friend was very right about the impending drastic price increase. It was at the end of the season and he was ordering stock for next years season because his suppliers informed him of the cost increases. Don't believe my stocking up had much to do with that.
