Now is the time to fill up.

Gas prices around the Iowa side of the Quad Cities have plummeted a whopping 33 cents in the last month, according to KWQC.

Pump prices in Davenport and Bettendorf averaged $2.33 at the end of November. Now you'll easily see gas for $2 a gallon around the Iowa side, with Davenport stations selling for as low as $1.87.

On the IL side of the river, gas is a bit more expensive due to taxes, but you can still fill up for just $2.13, a 40 cent drop from just a month ago.

The Wall Street Journal says nationally, prices are at their lowest price in a year and a half. The reason? High gas supply, falling oil prices, and a lower demand during the winter months. In other words, enjoy it while it lasts!
