I am going to be starting college in September and I am thinking of purchasing an iMac to help aid my studies and video editing work. Apple states on the main page for the Back to School promotion that the iMac starts from £880. However, when I add it to my basket in the Education store the base model rings up at £939.60. Does more discount get applied later on or what? I'm pretty confused and hope someone who has already purchased an iMac with this deal this year could offer some assistance.
