When should I begin buying for my unborn baby?

I started buying things at about 7 weeks pregnant. My baby's room was finished at 24 weeks pregnant. I am completely ready to go now at 31 weeks. I picked things up here and there until I had everything I needed as it was easier then forking out a ton of money at once. So I say start anytime now. As for the names...honestly dont like any of them. I cant even say the boys name or maybe I can but I'm not sure and if its said the way I think then its pretty bad. Addalyn is ok for a girl, but the middle names are spelt really badly and put together it kind of hurts my eyes to even look at them. Sorry.
