#236: Cash Gas Price Scam

I've started seeing this a couple times now. This latest time was in Twin Falls, ID where I stopped to get the cheapest gas I've seen in a while advertised at $2.72. When at the pump, the card reader said price was 5 cents higher for non-cash purchases but the sign said nothing about this. The electronic sign did, but the freestanding sign with the prices did not. Given the rarity of gas stations charging different prices for cash these days, I think it's borderline fraud for this gas stations to not boldly state that their cheaper price is for cash only.
