The K-Cups can get pricy but we shop around, Costco has good prices, and every so often Price Chopper or Target put them on sale. I subscribe to their website and get some of their specials where you buy 2 boxes and get one free or sometimes its free shipping, and you can mix and match whether you want tea or coffee. We've got the little filter for it too if you want your own special blend of coffee. Our machine comes with 3 different cup sizes, it will even make travel mug sizes, and ours also has the ice tea fuction which I've been wearing out with this heat!
