If Campbell's Costs Go Down, Why Soup Prices Going Up?

Earlier today, the Campbell Soup Company reported quarterly profits at higher-than-expected levels.  They cite two reasons for this unexpected boom to their bottom line - the cost of raw ingredients has gone down and the prices their customers pay for their finished products has gone up.  I ask, why, if Campbell's raw costs go down, why are our soup prices going up?

Oh, yeah.  It's that bulging bottom line.  Silly me.
