That is a good idea, I am flying somewhere else before then and I can check the Seatac airport duty free to see if they have it and just put it in my carry on after going through security. I know they don't have Hpnotiq, but I never checked for Fireball before.
You do realise TTR don't allow body shots anymore don't you? They clamped down on it last year. The TTR management are becoming more and more lame every year x
