If you think gas prices went up fast, you're right.  

GasBuddy's daily survey of 720 gas stations in the Sacramento area shows the average price at the pump shot up 6.1 cents per gallon in the past week.  

As of yesterday, a gallon of regular was, on average, at $4.10.

That's 25-cents higher than a month ago and 45-cents higher than the national average.
