Just reread that post. It reads a bit negative toward Rick. Sorry Rick, that wasn't my intent. Lets try this instead:
I have a hardware store near me that always sells lumber products at the same price. They take the amount that wood sells for when it’s at its highest cost during the year and sell it to me at that price plus their markup. On the other hand I have a lumber yard near me that sells their lumber for cost plus their markup. Sometimes it costs as much as the hardware store, but its price is always changing based on their cost.

Guess which store I buy my lumber from.

And of course, PTP, Clayton and Jake are right. It’s all market driven. If WM can sell a tube of goop for $25 and its 2 bux at your store, it’s your choice on where to buy it from and if the convenience is worth the difference in the price.
