Amazon's Mayday support button
J Thoendell stashed this in Tech
If you don't know, Amazon's Mayday button is a service tied to the new Kindle Fire HDX tablets, and allows for the user to be connected to an Amazon expert to help them through technical issues, questions they may have about their tablet, or change settings and other similar things. It's available every single day of the week, every day of the year, and it's totally free. No extra charges.
This is obviously a service that Amazon could charge for, especially to extend a warranty, but they don't.
