If you have a Home Depot nearby, they rent trucks for like $19 for the first 75 minutes. Go for a wood run, rent the truck for an hour, buy enough to make it worth it, and return it.

From what I've seen though, wood isn't cheap to have delivered. They can cut it for you in the store, but obviously a prius still isn't best to ship it in.

Maybe find a friend with a truck or light trailer that you can borrow every couple of months?
