You never want to feel like you’re leaving money on the table — especially when it’s missing out on cash back for everyday purchases like gas, groceries and dining out. That’s why I started using the free Upside app to get cash back on every purchase.

It’s easy to use — you just find the business where you want to earn, claim the offer, pay with a card saved in your Upside wallet, and “Check in” or upload a pic of your receipt. The best part is that it actually is real cash that you can add to your bank account, PayPal or a gift card. Plus, Upsiders earn 3x more cash back than with other loyalty or rewards products!

Here’s a promo code to get you started with extra cash back! Download the free Upside app and enter promo code KIM to get an extra 25 cents back for every gallon on your first tank of gas.
