I found someone selling 5 yr old blueberries on Craigslist. The seller has a friend in the East of WA who has a 'pick your own' farm and wanted to put in raspberries. So they were going to till an acre of 5 yr old blueberries. The seller grabbed 1800 plants, planted them for a bit, then was selling them for $25-45 depending on size.
I bought a $35 plant. It's a Duke blueberry and looking good, it has flowers already.
