Most times in this area Midgrade (E-10) is cheaper than Regular Gas. Usually the lowest price on the sign is for the Midgrade (E-10). There are only a couple of stations that have their Regular lower than Midgrade and those stations have E-10 in all their grades of gas. Thanks for posting prices.

Thanks bernie6161 from Omaha for posting Spearfish gas prices.

Thank you for recording Sam's Club gas prices the way in which GasBuddy has asked us to. Without member discounts.

You are posting midgrade price's either as costing more than Regular or Regular and Midgrade as the same price. Please read the posting guidelines and post prices correctly. The stations you posted as having both Midgrade and Regular as the same price is incorrect and considered as posting fake prices.

Are you sure that Sam's has Regular cheaper than Midgrade? That is not the norm for this area. If it is correct please note that "Regular is cheaper than Midgrade" in the comments section as per the posting guidelines.
