It's just the opposite for us. We use the Keurig for the convenience of just one cup, but for company we make a whole pot because so many are drinking it. I use CoffeeGiant
http://www.coffeegiant.com and pay $13.32 with free shipping for decaf. Not sure if decaf is more expensive or not other places, but it's what I drink so it's all I know. I like their selection and they have sales on different kinds sometimes. Works for me but I have so site loyalties so if someone has a much cheaper price I could be convinced to switch sites for my coffee. I am only using 2 cups a day and don't mind using the machine which I keep in my office at work. It's so much easier then having to make a small pot and dealing with grinds, filter and dumping the mess. I just can't bring myself to use it to make tea for the higher price, though, although I do use it to make hot water and then use a tea bag.
