Rick, I am truly sorry that you got taken advantage of with the gas thing especially since you were helping someone else but to compare this to that situation?? ....c'mon dude...... to liken that to me charging less than fair market value for trailer sensors that someone else is happy to pay, just doesn't hold water. Clearly the buyer didn't feel taken advantage when he bought them and still doesn't after I kept my word and sent them when I said and how I said even though he prepaid for them...the fact is that no one forced him to buy them, just like no one forced you "overpay" for that 3 gallons of gas, correct? No one forced him to agree to the price but none of that really involved you to that level (Proverbs has a great verse on meddling...check it out Proverbs 26:17). I really don't have a problem with you letting people know there are knock-offs available on a thread that I started, no problem at all.. but again, to liken it to "getting punch in the gut" is ridiculous and amounts to a feeble attempt to stir up trouble. I have been taken advantage of just as everyone has at some point so I would not want to do that but I would also not want to judge every future transaction through that lens either. I have no hard feelings about it as it seems everyone is happy but you. Have a good day.
