Grocery bills may stay up, regardless of falling oil prices

According to CNN.com, the recent drops in the prices of oil, while relieving, may not mean a drop in prices of all commodities, at least, not yet. Due to the company setting prices on the commodities that it sells, prices on items such as a box of cereal, and a gallon of milk may go unchanged for weeks. These are called "sticky" prices, where the cost of the goods sold does not change on a day to day basis, much like other products, such as oil. What this means is that consumers will still see higher prices on food and other goods, at least for a little while.
