Gas Saving Tips for Laramie Drivers

Fill up on Monday or Tuesday mornings — gas prices typically rise Thursday through Sunday as weekend demand increases, then reset lower early in the week.
Use the GasBuddy or Waze app to compare prices within 5 miles of your location before every fill-up. Even a 10-cent difference on 15 gallons saves $1.50 each fill-up.
Join a warehouse club (Costco, Sam's Club, BJ's) — their fuel consistently runs 10-25 cents below local market prices. The membership cost typically pays for itself in fuel savings within the first two months.
Sign up for gas station loyalty apps — Shell Fuel Rewards, Marathon MakeItCount, and Circle K Inner Circle all offer genuine per-gallon discounts that compound over time.
Use a gas rewards credit card. The Costco Citi Visa earns 4% back on eligible gas; Blue Cash Preferred earns 3% at US gas stations. Pairing a reward card with a warehouse club maximizes savings.
