The Triple-A Texas Weekend Gas Watch says the statewide average gas price in Texas is $2.84 a gallon for regular unleaded. That price is one cent lower than a week ago, and is 97 cents higher than a year ago. The national average is $3.18. Lower demand resulted in more supply, contributing to the cheaper national average price. If these trends continue to the end of this month, pump prices will likely keep dropping as the Labor Day weekend approaches. The average price at the pump in San Antonio is $2.71.
