Last time I was out and about, I think it was like $3.55 for regular. Even at these prices, I could fill my motorcycle up (Not riding at the moment, but will next week) for around $10 and go 200 miles on it.. More people should ride, but I digress.
Yesterday I paid $4.39 in Simi Valley, $4.09 in Buellton and $4.29 in Sacramento. Always fun driving I5...not. Interesting that it was cheaper in Buellton than the other places.
Here it was about 3.42 last week, this week it's dropped to about 3.34. Lowest I've seen it. It's probably about 10-20 cents cheaper in SC from my experience at least.
