There's no tax, since it's a form of interstate commerce. Maybe FoolKiller had to pay it, since he's also from The Bluegrass State. With a website owner in one state, hosting in another state, PayPal in another, it's kind of hard to pick a point of origin for sales tax.
In any case, I didn't have to pay sales tax on my purchase of Premium, so you can rule Florida out as requiring to pay sales tax on the purchase.
Go and "engage rant mode" and flame everyone. Make a big fuss about it too. You'll be remembered for all time as the member who lasted the least on GTP after turning Premium 👍
If you go Premium it's because you respect GTP and want to contribute more to it. Or you can do what a few members have done which is pay the minimum just to be able to have their username changed. But in any case, you shouldn't go Premium just to be able to make an ass of yourself in one more forum.
I was just kidding around... I wouldn't spend $48 just to flame people over the internet, but rather to support the community, help Jordan pay out a tiny bit of the costs, and thanks Danachronism, the things you said there really makes me want to change.
