I saw $2.09 yesterday in Omaha. Crazy! I did not ever think gas prices would get that low again. We do most of our shopping through Baker's (Kroger) for fuel points and it's so weird to see it get below $2!
Yeah, we're at $1.94 at our local Costco in Richmond, VA but I was in Arlington, VA last week and gas was $0.50/gallon higher (only 90 miles away). Taxes make a huge difference.
The $1.75 at Sams is in Baton Rouge, Louisiana. I'm not sure if it is just our Sams. Costco just opened their first store here and they are having a bit of a gas price war.
