It should have said in big bold letters that you can only use "PODS" in this coffee maker. Granted it is called a pod coffee maker (& I may be an idiot for not knowing what that meant) but I wasn't expecting to have to special order very expensive coffee that is shaped like little frisbees just to have my morning cup. All I want is a bag of coffee & a coffee filter. Having to use these little pods greatly limits the selection of coffees you can choose to drink.
