Yup, you read that right.

Thanks to the GasBuddy app, Phoenix drivers had the opportunity to score some free gas on Nov. 2.

As part of GasBuddy's "Tanks"giving event, the free gas was given out at a "secret" Corner Store/Valero location in the Phoenix area.

FIND CHEAP GAS: 12ne.ws/gas

Here were the important rules of the contest:

- Drivers interested in participating must have the free GasBuddy app downloaded and a profile created.

- Only $20 worth of free gas per vehicle.

- You can not bring any external containers like tubs, buckets or jars to fill up with gas.

- The promotion is only available while supplies last.

Phoenix was the first stop in GasBuddy’s nationwide "Tanks"giving event. GasBuddy is an app that shares consumer-reported prices of nearby gas stations.
