Use the Free Upside App to Save on Gas — Earn Up to $0.25 Off per Gallon

The Krazy Coupon Lady is an ad-supported service. Many offers on our site contain affiliate links, and we may earn a small commission if you make a purchase using them. Some posts are sponsored by the maker of the product, and we receive a fee for the post. See our full advertiser disclosure.

Gas prices can add up fast, but you can save by downloading the free Upside app. It offers cash back every time you fill up, helping you cut down on everyday expenses.

New users can score extra savings, like up to $0.25 cash back per gallon on their first fill-up with the promo code CACTUS25.

You can also use the code CACTUS5 for a $5 cash-back bonus on purchases of $10 or more, or CACTUS10 to get an extra 10% cash back on your first $10+ order. This app is free to download, so you can't lose.

How to get the deal:

  • Head to Upside’s website on your mobile device and click “Sign Up” to download the app. If you're on a desktop, you may see a QR code pop up after clicking "Sign Up." You'll need to scan that code to download the app.

  • Set up your account by using your email. You can also create an account by linking your Google, Apple, or Facebook account to Upside. 

  • Depending on your personal preference, you’ll want to enter one of these three promo codes:

    • CACTUS25 for up to $0.25 per gallon cash back on your first fill-up

    • CACTUS5 for a $5 cash-back bonus on your first purchase of $10 or more

    • CACTUS10 for an extra 10% cash back on your first order of $10 or more. (Note: This code has a maximum savings cap of $10.)

  • Choose your gas grade and click “Create Account.”

  • Allow the app to track your location to find offers by clicking “Continue” and following your device's prompts to grant access to your location.

  • You’ll need to link your debit or credit card to receive the cash-back reward when paying for your gas. To do this, click the three lines in the upper right corner, select “Wallet,” and then “Add Payment Method.”

  • Now you just claim an offer in the app at a supported gas station near you. Head to that location and fill up your tank using the debit or credit card stored in your Upside wallet.

  • Tap “I’ve Paid,” and your cash back and bonus savings will process within two to four days.

What is Upside?

Upside is a mobile app that lets you save on everyday purchases like gas, groceries, and dining. When you shop at participating locations, you earn cash-back rewards that you can redeem for cash or gift cards.

The fine print:

Bottom-line cost: The Upside app is free to download. You won’t pay anything more than you normally would for gas. No payment is necessary to use the app or to receive your cash-back rewards.

How do I get my cash back? Once your gas purchase is confirmed by Upside, the cash-back reward will be credited to your account in the app. You can then redeem your cash-back rewards for cash or gift cards.

Do I need to cancel? No, Upside isn’t a subscription service, so there’s no need to cancel.
