Normally, I'm a coffee snob. I enjoy buying Fair Trade coffee that's delivered on the backs of donkeys that is then eventually air roasted as opposed to machine roasted in bulk. I like to grind the beans myself when I want to make a fresh pot. Then I brew it with one of my French presses following a ridged set of steps to ensure I get the most out of my coffee. Unfortunately all of that takes time. When I'm in a rush or want a quick single serving I usually give up and either go with a Folger's bag or else a Starbucks VIA packet.
The Keurig makes it just as simple, it's faster with no mess and there's a wide variety of coffee. Almost every grocery store, Target, Walmart, etc. carry the cups. They come in brands like Starbucks, Folgers, Green Mountain, Gloria Jean's, etc. There's also a good variety so I can start off in the morning with a bold cup of coffee, the kids can enjoy hot cocoa and Shannon can have a decaf tea before bed. You can view all of the different coffees on their website.
My commute with work has gotten longer so being able to make a quick cup of coffee on my way out the door has been great. On the days where I work at home I still enjoy the French press. At other times where I want something quick or someone else in the house wants something other than coffee the Keurig has been a great addition to my pile of coffee appliances and accessories.

My other big source of coffee from the holidays is the Starbucks tumbler pictured below. Starbucks always has their 12 Days of Christmas sale where they offer some really good deals on coffee and accessories. The best deal they had this year was the tumbler for $19.99. Normally the tumbler sells for $10, but if you bought it on that particular day it came with free coffee for the entire month of January. So far I've enjoyed a free cup of coffee each day. If you figure a venti sized coffee is usually around $2.12 if I drink a cup of coffee a day that's $65.72 overall. While it's not the greatest looking cup it does a great job of keeping the coffee warm.
