David Conti / TribLIVE Business – The sight of Western Pennsylvania stations selling gasoline for less than $3 a gallon five weeks before Christmas should bring joy to the holiday.

For some people, it’s not enough to fuel a shopping binge.

“It’s meant I can put more gas in my truck because it was so expensive for so long,” Erick Williams, 43, of Brighton Heights said as he filled up at an Exxon station in the North Side. “In the next couple weeks, if it stays this way, maybe we’ll have some extra left over.”
