Stock up on chocolate now, because after the new year it is likely going to cost more. Hershey announced it is going through with a planned price increase early next year to offset increases in commodity and shipping costs. The candy company said it would raise prices of some of its products by about 2.5%. It also has other changes in the works, including a Reese's Thins, which would be a 40% slimmer peanut butter cup. It has also purchased some healthier products, including Pirate Brands.
