Yes, you can use whatever card you already use for gas (besides Fuelman or Fleetcor cards), and pair your purchase with other promotions. It’s important to note, however, that if you use a rewards card or other promotion* alongside Upside, your Upside cash back per gallon will be reduced to account for the cost of the other promotion, or if the outside offer is higher than the base offer, you will not be eligible for cash back.
This adjustment to account for other reward programs is something we've implemented at the request of the gas stations we're working with. They've raised the issue that the Upside program, when layered with their existing rewards programs, can result in them losing money. We do this adjustment to ensure that the Upside program works for the gas station just as well as it works for you. Happy merchants stay on the app, which means more places for you to earn cash back. You can still stack programs, getting you more savings on gas than just using one program.
As a reminder, when gas margins are tight for merchants, your offers might not be as high. However, margins always recover, so we encourage you to continue to check the app.
Lastly, if the base offer in Upside is fully removed due to your outside discount, the entire offer (bonuses/promotions included) will not process. Please note that any bonuses/promotions will remain on your account for your next successful gas offer.
