Upside is an app in which you get cash back on gas. All you have to do is upload your receipt. You can redeem the cashback for a gift card starting at $10 or use Paypal. PayPal has a $1 fee if it’s less than $15.
Use the promo code: F3HS4 to get $.15 off your first fill up.
After your first offer cashback per gallon will vary. Currently mine says $.10 off gas stations in Vinings
