Great store in the Forum shops. One of the biggest Apple Stores I have ever been in.
Discovered the self scan checkout system here for my new iphone case. You scan it from your phone and your receipt is e-mailed to you. No need for a sales person and you just walk out without security giving you a second glance. (I am sure they have some type of technology that identifies that you have made a purchase but I couldn't figure it out.)
