Those headed to the pump in the Bay area are seeing some price increases.

The price for regular unleaded gas is averaging $3.81 a gallon, according to AAA on Saturday.

That number though could inch up as we start to see more stations jump over the $4 mark.

Last month, we were paying $3.34 a gallon; that's a $.47 jump in one month, making this February one of the biggest spikes in gas prices we've ever seen.

We are now edging closer to the all-time high average price of $4 a gallon.  That was set back in July of 2008.

Local drivers are once again making decisions based on saving gas.

"I'll be riding the bus all day long,” said Tampa resident D’Andre Peacock, “only take my car when it's necessary."

Another Tampa resident, Nick Kalomeres, said he’s already struggling.  "I'm already carpooling, and gas is pretty ridiculous. I just bought this car and I'm already flat broke," he said.

So why are the prices climbing so quickly? 

This time of year gas companies are transitioning to a cleaner burning fuel for the summer months, that costs them more money.  It could take a few weeks to a month before that transition is complete.
