GasBack is GasBuddy’s rewards program that allows you to earn rewards in the form of gas from the purchases you make. It’s like “cash back,” only the currency is gas for your tank! How are we able to do this? GasBuddy works with leading brands that provide incentives to promote their products and services. GasBuddy is committed to helping you save money on gas, so we pass those incentives along to you in the form of GasBack Rewards.
