I was excited when AAA changed its partnership to Shell and offered $.05 / gallon discount to members. Then, T-Mobile bought Sprint and gave me another weekly discount at Shell. Now, I also started using the Getupside app for another discount on fill ups, and you should, too.
While my Shell rewards doesn't allow me to fully stack the rewards, I do get "cash" back from Getupside that can be used for Amazon or Walmart gift cards. Instead of the normal $.12 per gallon, I get $.085 per gallon while saving $.05 at the pump, for a total of 13.5 pennies back per gallon. When gas is as low as $2.00 a gallon, that's a decent 6.75% off. I'm also not limited to Shell with Getupside, so I can just take the $.12 per gallon at a cheaper gas station that also offers my preference of top tier gasoline, though I have yet to research which local ones would be my best bet.
If you are currently driving to help make ends meet, using Getupside is a total no-brainer (unless you're using an EV). Your Uber, Lyft, Door Dash, Postmates, Grub Hub, Roadie, etc., runs will be at least partially offset by gift cards to buy the necessities.
You're not going to get rich by saving money on gasoline, but if you drive a lot, like me, you might earn $10 gift cards every 2-3 weeks, and that's something, which is better than nothing.
A friend of mine signed up and got around $.30 off per gallon on his first fill-up and then he has an opportunity to earn another $7.00 for friends of his who sign up. It's like a pyramid scheme, except you don't have to buy products you don't need to store them in your garage and hold fake parties for friends you don't like to sell them products and an opportunity to be in your downline.
Also, I wanted to mention that you don't have to give Getupside your entire credit card number or bank information, but the process is kind of clunky as a result: you have to claim a discount in the app, then check in when at the gas station, then choose the partial credit card number being used, then wait two days to see the reward. It's better than taking photos of receipts, which was the original model, but still clunky. That said, it's a decent discount off something you need if you drive a gas-powered vehicle.
[UPDATE]
I was able to cash in my first gift card. I chose to add it to my Amazon balance, just to test it out. I also received the money for referring a friend/reader of this blog, so thanks. Everything about Getupside seems to check out, so it's a full recommendation. Just be aware that it often takes several days to see your cash back. And it's small increments, but worth the effort to me.
