Remember when gas was under a dollar a gallon?! Man that ages me. Long gone are the dollar gas days, so where do you get the best bang for your buck at the pump in Idaho?

This may come as no surprise, but Costco is the cheapest place you can find gas in the state according to a new study by msn.com.

The average price for a gallon of gas in Idaho is $2.55. At Costco gas is a full 20 cents cheaper, sitting at $2.35/ gallon. Of course the only stipulation is you have to have a Costco membership.

If you are not a member I have also found that the Fred Meyer loyalty gas rewards work really well. I don't even do my regular shopping at Fred Meyer, but I frequent there enough that I usually earn 10 to 20 cents off a gallon every time I go to the pump.

Albertson's also has a gas rewards program, so that's another good option.

Go save that money at the pump!
