I've browsed through your support site so I'm mainly after a quick confirmation from you: a friend of mine would like to create a blog with business content to advertise her really small shop. As far as I could check that type of content is OK to publish on a WordPress.com-hosted blog.
On top of that she would like to register a .co.nz domain for that blog. I think as soon as she's done that she just need to pay $13 a year to WordPress.com to map that domain to her blog.
Could you please confirm my assumptions?
