Professionals must be decent people, first of all. To become a certified requires some investment of time and money. When you achieved the goal, be proud. It's like the real estate investment: you spent money to buy, and later you sold with a profit. You would not get profit until you invested your hard-earned money. No doubts, everyone of us wants to spend less and get more. But the truth of life suggests that it's not always possible.
I usually buy the Transcender exams from this source:

and I never regret because they sell #1 software at the best around price. Also, I know that you can install the Transcender's software 3 times at different PCs (home, work, laptop).
If you want to re-sell it officially through the web, it's not permitted in addition to the need to activate it over the Internet with Transcender's web site.
As to those forum members who speak the only F-language, I believe the moderator must clean this garbase out of the forum as I do it at our forum.
