Has anyone purchased "refreshed" stock from an Apple Store? My understanding is that if they have stock that has been returned to the store, they will sell it to you, discounted 10% that they charged as a restocking fee to the person the returned it. If you are eligible for the edu discount, you get the additional edu discount on top. Sounds great, if you can get the model you want. Anyone know how this works and how likely I am to find a 20" iMac that way?
