Of course the illuminate would want you wear the foil hats ineffective for chem trails. I'll bet it doesn't even attenuate the lizard people thought control.
I'd just like to say this is categorically false advertising if there isn't an actual hat inside. If they included extra foil for the hat the amount listed on the box would be incorrect. If they didn't include extra foil, or the label said the correct amount of foil, then there's no free hat. Those are completely mutually exclusive cases, so if there's no hat, easy false advertising lawsuit. You deserve the free hat they said you were getting.
