'cheats' is the definition.
('rip off' can be a synonym of 'cheat')

'epitaphs no longer available' is the wordplay.
'epitaphs' becomes 'rips' (I am not sure about this - if you are sure you should believe this answer much more).
'no longer available' becomes 'off' (I've seen this before).
'rips'+'off'='RIPS OFF'

'for' is the link.
