I've been using the Upside app to save money on gas and have a referral code to try for yourself. You'll get up to 25 cents per gallong cash back on gas in addition to this bonus by using my referral code. That's up to 40 cents per gallon in total cash back. Use this link or my referral code JASON63768 to get an extra 15 cents per gallon in free gas the first time you use the app: I'll also get an extra 15 cents per gallon after you use the app, so thank you!
