Last week Robert Downey Jr. revealed on Facebook that his choice in single-serve Keurig-style novelty coffee makers is Iron Man-themed. This much is not surprising. However, you don't need to be a billionaire genius to get your hands on this Tony Stark-approved technology. So you can enjoy a cup of hot, caffeinated bliss straight from Iron Man's throat for 13 percent off the list price! The Iron Man single serve coffee maker provides the flexibility to brew either coffee capsules or ground coffee.
