Gas prices vary according to a number of factors. Location, season and the price of crude oil all contribute to the price of gas at any given time. GasBuddy.com is a website that displays the lowest prices for gas within any region. Users can search the site by ZIP code.
The price of gas tends to rise during peak travel times. Holidays and summer often bring with them increased gas prices. A jump in fuel prices during the summer is partially due to the fact that summer gas is formulated to emit fewer pollutants than its winter counterpart, and it is more expensive to produce.
