GI Joes. They have a few stores in town. The one I go to is on Boones Ferry.

Go here for the store locations:http://www.gijoes.com/corp/index.jsp...cator&state=OR

I was there yesterday and they are having a sale on AMSoil. Not a huge discount... less than $2 off. There's a way to get it even cheaper I'll tell you in a PM.
