Addon trial

Hi,

I'm considering changing our company video player into JW Player, however we do need a lot of addons, such as AdTonomy.

Of course, I can buy these licenses, but before spending money, I would like to check them out, and see how they works and how they are administered.

Also - maybe - I would like 'Flow', but don't want to pay for it, without knowing exactly how it works...

I it possible, or do I have to pay, to try it out???
