As per Gas Buddy policy-

The only time you should post the cash price as the primary price is if the station does not accept any plastic at all. Since we're seemingly moving to a cashless society, we ask that you post the credit or non-discounted/non-cash price as primary. Feel free to list the discounted price or cash price... but as a comment, as you're allowed. Only credit or "once price" goes in the price posting fields.

Thanks for posting!

The poster below does not work for GasBuddy. Also, his info is incorrect. GasBuddy allows for posting of cash prices. Check out the forum
