It won't make a difference, there is no significant amount of people to do it, and it'll make the others jack up the prices because they can cause we're buying from them... I buy from citgo cause that is the only non-middle-eastern company within 10 miles of me, and moreso for the $0.15 off per gallon I get just by using a giftcard. Citgo or Sunoco that's it for me if I can help it.
It'll clear up after this election, and also once we get some of our OWN oil pumping out of the gulf by late next year.
