This is the cheapest I have found in my travels. It is $2.29 in my city now. The price you see below is out in a county area. I have seen lot's of independents that have mini-marts practically in a price war. The farther out it is, the lower the price. This is not normal!
What it points out though is that we have a few forces at play...greedy merchants, and local taxes. The pictures below are in Los Molinos California in Tehama county on Highway 99. Los Molinos is around 15 miles north of Chico which is averaging $2.25 for regular. Chico is in Butte county.
Looks like it's time to petition local government to reduce fuel taxes to stimulate the economy!
