I wanted to know why the Sam's Club store in Butler, is always cheaper when it come to Gas prices. All Sam's gas should be the same price. Sams at the mills store was $2.74 and the Butler Sams was $2.64 a couple of weeks ago I was there shopping. :(

Possibly due to Allegheny County taxes and fuel additives required for air pollution control within the county. Not sure.

I see the same. Check on the app __ GasBuddy for the lowest price one.

I believe pricing is derived from actual delivery and market conditions. Naturally a business cannot sell any product less than it's wholesale cost.
