3 days ago, I filled up my tank with unleaded gas at the Circle K by my house at the corner of Montwood and Trawood on the east side of town. The gas was listed at $3.09 a gallon. Today, as I was headed to work,  I noticed it went up to $3.17 a gallon. A half mile down, at the corner of Lee Trevino and Vista Del Sol, another Circle K store had unleaded at $3.29 a gallon. What gives ??  The same franchise, within less than a mile apart, and the gas price was 12 cents a gallon more !! Let's all rally together and share gas prices. Every couple of days, I'll post the best price I see for gas, and let's compare.
