Let me glide noiselessly
  forth;
  With the key of softness 
      unlock the locks -- 
      with a whisper
  Set open the doors, O
   soul!
               Walt Whitman

Your Least Expensive Option

Your least expensive choice of funeral is what the funeral industry calls IMMEDIATE DISPOSITION. 

It is a cremation without a service.   

Price is further reduced by accepting the cremated remains in the container provided by the crematorium and scattering the  ashes personally.
