Here are Walmart.com’s instructions on how fuel works on Exxon:
Key Point: Must be a participating exon or mobile station. You must have the app installed on your phone and location services must be enabled. You will need to pay with the pump using the same card you use with your Walmart+ account. And yes, you can use the discount multiple times a week for discounts. Do you forget how to do that? Go to the app and find the gas discount in the Walmart Week Perks scrolling menu. Click on more for step-by-step directions. This is the simplified version.
