Hello all, I'm planning to buy a new Macbook Air. I have an educational discount since I'm a university faculty member, but since I was thinking of visiting Portland, OR at the end of the month (I'm a Washington state resident), I thought maybe I can save even more money by picking up my order there. Has anyone from Oregon's neighboring state order a custom config Mac online and choose to pick it up in Portland's Apple Store? If so, did you have to pay sales tax? When I chose to pick the order up in Oregon through the Apple online store, the sales tax disappeared from my order, but I want to make sure and hear anyone else's experiences. Thank you.
