funny story on my way to work today. most places here are now at about 3.85/gal prem. i was at a light and the corner station had prem for 3.79. i thought to myself, i need to get some of that at lunch. while i was waiting, the sign changed to 3.89. i immediately turned around and went across the street to full up at the competing station still marked at 3.79 because i know they will raise theirs before lunch. these changes are crazy. no rhyme or reason. it's not based on their cost because they change more than once per day. it's just crazy - though my energy stock is performing well.
