S/O - How does the gas a costco work?

[AngB]

Probably depends on the area. My Costco is consistently .30/gal cheaper.

Wow! It must depend on the area. I know our state usually has below-national-average gas prices so I wonder if that's what makes part of the difference. At 30 cents a gallon less we would NEVER get gas anywhere else. It is slightly somewhat out of the way so we just try to do it there most of the time but our savings is not usually that big of a difference.

I have never seen gas much lower than a couple of cents at any Costcos in WI (although I haven't been to the one in Green Bay). WI does not have inexpensive gas, especially where I live.
