If you are a member of a warehouse club (Sam's, BJ's, etc.) that sells gas, it is not uncommon for their gas prices to be 20 to 30 cents per gallon less than "gas stations". We easily pay for our Sam's and BJ's memberships just with our savings on gas purchases. In Dayton, there is a Sam's club that sells gas just west of I-75, just South of I-70 (take 75 South from the 70/75 intersection, and I think you get off at the first exit, it's a bit further south on the west side of the surface street that runs west of I-75). There are probably other locations and other wholesale clubs, but that's the only one that I know of. Debating now between going tomorrow (Friday) or Sat, weather looks better for Sat.
