Re: Taxes, Affiliates and Theming...
You have the option to select Australian currency within ClassiPress, so this won't be an issue.
There is no affiliate integration at present, and I don't know if it's something that is likely to ever be implemented down the track? I can find out more and will let you know.
ClassiPress is a theme, not a plugin. If you install CP on an existing
WP site it will take over the existing theme. If you have enough coding knowledge it should be easy for you to customize the theme to your requirements. I agree the showcase itself is a little out of date, as it went up early on when the forums first started, but there are definitely some amazing customizations out there that look very different to the out of the box theme.
You could check the showcase and feedback thread for more recent examples
http://wpclassipress.com/forum/viewforum.php?f=3. Some great looking ones I have seen recently include:
http://www.boardjoy.com/, and
http://runninghorses.net/ to name a couple..
If you weren't aware, ClassiPress 3.0 is to be released in the near future, and the look of this is again very different to the existing theme (as well of loads more features). If you are planning to purchase CP, I would suggest you do this before the nest version comes out as the licence prices are set to increase. Since upgrades are free, you will be able to get 3.0 at no extra cost.

Hope this info helps :D
