Query: Robbery

The cost and lack of availability of these filters is robbery. If I had known about the problems and cost involved in finding them in the first place I never would have bought a mr coffee, and in the future I will be very skeptical of mr coffee. If I tried to replace the filters from the mr coffee web site at the suggested rate of one per month it would cost me about $60 a year.
