Need Help with Message Body Filtering using AND/OR, Nested If conditions

Hi,
I am new to procmail and would appreciate if anyone can
help me with real code of .procmailrc for the following example:

In message body search for :
search for the word Item
if found
      search for the word TV or VCR
         if found
            search for the word price or pricing
               if found
                  put the message in the folder tv-vcr-rice
               endif
       elseif search for the word radio
          if found 
             write the message to folder radio



 ----- and so on

I can be reached at dvazirani(_at_)attmail(_dot_)com and my
tel is : (201) 267-4163  (country USA).

Thank you very much.
