There's a shop in Everett on Hewitt down next to the freeway that specializes in reptiles. I've gotten feeders and a couple of supplies (repashy food and such). They'll probably have something you can pick up in a pinch

I think there's another shop down in Puyallup, but I haven't been down there to it
Edit: Here's the Puyallup shop's info
