New tales are a bargain (5)
I believe the answer is:
steal
'a bargain' is the definition.
(I know that bargain can be written as steal)
'new tales' is the wordplay.
'new' indicates an anagram.
'tales' with letters rearranged gives 'STEAL'.
'are' acts as a link.
(Other definitions for steal that I've seen before include "Purloin" , "a snip!" , "Take unlawfully" , "Take illegally" , "Shoplift" .)
