Everyone from Michigan has been on a gas price roller coaster for the last few years. No way the gas prices can go up the exact amount on the same day, within about 3 hours, the whole west side of the state has adjusted to the new price, usually up between 15 and 20 cents per gallon. Then over the next week it would work its way back down a little, and then ZAP, everyone jumps again.
I filled our boat (31 Wellcraft Express Cruiser = SLOW, but not trailer-able) at the marina 2.5 weeks ago for $2.09, turned out to be a great deal, now that mid-grade is $2.29 at the street pump.
What are you gonna do? Pay it and smile.
