For the second year in a row, U.S. shoppers are seeing double-digit inflation in the candy aisle. Candy and gum prices are up an average of 13% in October. That’s on top of a 14% increase in candy and gum prices in October last year. Weather is the main culprit. Cocoa prices are trading at 44-year highs after heavy rains in West Africa caused limited production in the season that began last fall.
