Memorial Day Weekend already has the potential to be expensive with all the travel and food purchases. So, saving money where you can is essential. 

Gas can easily be one of the most expensive parts of the weekend - unless you are springing for the finest cuts of steak - and if you don't look around you could be spending up to 40 cents more per gallon in Idaho.

GasBuddy is one of the best and easiest ways to know where the cheapest gas is in Idaho. Currently the cheapest gas in Twin Falls is at the Costco on Poleline at $2.29 a gallon, after that it's $2.32 at the Sinclair on Addison. Average gas price today is $2.56. This is being written on Thursday afternoon, so these prices may go up in the next day or even hours as we get into the holiday weekend.

Gas Buddy even has an app to help you since you are probably going to need this info while you are on the go.
