How to buy PT3

[bogracs]

I know this is probably a very dumb question but I really can't find where I can buy PT3 Holdem. I am still using the 60 day trial and it will soon expire. I've only found a page which offers an upgrade but I don't have a valid key. I still can't afford the PT4 and I was wondering what I can do. Thank you.

PT3 is no longer on sale, only PT4 is on sale at this time.
