I already own ST2 or do I have to pay again to get ST3.
Yes, version 3 is a paid upgrade. Please keep in mind that the price for version 3 will double on october 1st. Currently the price is reduced to give existing users a chance to upgrade without having to pay the full price. But this offer will expire in a few days.

If you purchased version 2, you can always download it again by opening your account page in the app store and going to your previous purchases.
