Squaretrade is offering 30% off today no limit on the discount, use code DEAL30. You have up to 90 days after purchase of a new item to buy a squaretrade warranty. I bought our mini when mac connection had it for $599. I used my AMEX so right now we are covered for 2 years. I can get square trade warranty for 4 years total (additional 2 years) for $77. If I did not have coverage from AMEX, I would not hesitate. I know Mac's in general are very reliable, but 4 years is a long time for something not to go wrong.
