Walt, you're barking up the wrong tree if you think John is trying to pull a fast one on you. I know John for a long time now, have had many dealings with him, and will back him up against most anyone. He is fair, honest, and believe me, he doesn't need your $5.99 to help make his house payment.

Just cool off and let John make everything right with you. He does not deserve a negative feedback due to an unintentional mistake.
