Rex, It bounces like that all the time here. If you get gas mid-week, it's usually the lowest. Friday night the sign said $2.86. Not paying attention to the pump before almost full, it was at $3.049.

Picked up some diesel for the tractor, that was $4.09. I can get off road stuff, but not on Saturday in the area. I won't buy it from the station a mile away... trust me!
