I bet they are already sold out. When I wanted to buy a second N900 in phonehouse when they had a clearance, it was selling for less than 300 euros, maybe it was 200 (don't remember exactly, but couldn't believe the price), they sold out in 2 hours. Couldn't find one, staff had probably bought them. As for new N9s, in my country the price range is from 250-300 euros.
Just wanted to let you all know that here in belgium Phonehouse has N9 clearance sale and is selling brand new ones for 250euros.
