When should I be getting a domain?

That's a nice and reasonable deal.
Wish all domains were like that though.

I think you should buy one at the start. They're really cheap so you might as well.

if you don't have much money then i suggest save up some more for that domain you want

When you start out.

You should definitley get a domain if you can afford it. If you can't then see if you can get a subdomain that you can 301 latter. I think you can do this with blogger, but it is worth checking
