Cheapest around me I've seen is 2.89 for regular and 3.39 for premium (91). That is at an Arco station. I've seen most gas stations around 3.2X range for regular.
Doesn't seem like gas prices have gone down much in my area.
San Antonio update
129 87 now at some stations.
I remember super was 150 in 03 when we got car. Sunoco 94 was 170
