I do and love it. Have had one for almost three years now. Well had a Keurig but Cruisant at the PX. Gave my Keurig to my son.
If you go to keurig.com and buy from there you can get free shipping and earn points to buy stuff at a much cheaper price.
In the stores they have a 12 or 18 kcup per box and you can go to the website and buy the 24 kcup per box for less money or about the same amount as the 18 kcup per box.
I just bought a boat load from there as a member with my 15% automatically off, plus 1 sample (5) for every six boxes I buy and also got an additional 20% off for Black Friday which ended Monday of this week. With what I ordered I saved myself $72.00.
You may want to check it out. Also be sure to register your unit so if you have a problem it will be guaranteed. They are good about replacing them if something goes wrong with it.
