Gas stations cannot have their price lower then their cost, using it as a loss leader for other business. Gas companies aren't pushing it higher, they're just passing costs on to you.
A one day boycott? Please, what do the truckers do, what do delivery people do, people on cross country vacations, metro transit, etc. The simple facts are gas is still cheaper then it was 2 years ago, and ifa it'* such a problem for you, then you should re-evaluate your driving habits.
