 The consumer price index, an overall measure of the cost for goods and services, shows prices 3% higher in June compared to a year ago. That's a bigger drop in inflation than expected. Prices went down month over month by 0.1%, also better than analysts expected. Cheaper gas prices held back inflation despite small increases in housing as well as food prices at the grocery store and dining out. Analysts say the numbers could help the Federal Reserve decide to start lowering interest rates.
