How to save up to 40 cents per gallon on Thursday

Convenience store chain Circle K is offering special deals on gasoline in some states before Labor Day weekend — and in some cases, you have to be on time.

This Thursday, members of Circle K's Inner Circle Rewards loyalty program in Arizona and Nevada can save 40 cents off the price of fuel per gallon all day long as part of the Inner Circle Fuel Celebration, marking one year of the loyalty program's availability in those states.

In some other states, Circle K offers special price reductions at certain times of the day. For example, in California, Oregon, Washington and Texas, you can get a discount on gas from 4 p.m. to 7 p.m. local time.
