SAN ANTONIO -

It's the surprise at the gas pumps that drivers haven't seen in more than a year: a gallon of regular unleaded fuel for $2.89.

The Shell gas station on the 7100 block of Harlow Drive is offering the special price to customers paying cash.

Al Gonzalez told KSAT about the bargain on Facebook Friday night.

There's no word on how long the lower price will last.

The average gas price in San Antonio was $3.27.
