Which Place Has The Best Cheap Gas Prices In Yakima?
The other day, I saw the gas was $2.63 on W. Nob Hill Blvd, but the next day it was back up to $2.70-something!
UGH!
I found this website (Gas Buddy) to help locate the place that has the best cheap gas price in Yakima, but I am not for certain how reliable the prices are...
