Just received this note from WD (thank you!):

Just FYI: West Seattle Nursery just marked all big trees $10 and small ones $5 about an hour ago – although there are only a handful left. Got myself a real nice one!

We called West Seattle Nursery to confirm and they say it’s true – but they also note that as of this moment, they have only nine trees left. They’re open till 4 pm
