I just got off the phone with Apple to purchase AppleCare+ for my 2019 5K iMac and was informed that the cost with Edu discount has increased from $135 to $159. This increase has happened fairly recently, as I purchased the iMac at the end of September and the price for AppleCare+ at the time of purchase was still $135. From what I was told and can verify myself, everything about the plan and what it offers is the same, so the price increase offers nothing additional for the increased price.
