Reproduce lease incorporating half of prices (7)
I believe the answer is:
reprint
'reproduce' is the definition.
(reprinting is a kind of reproducing)
'lease incorporating half of prices' is the wordplay.
'lease' becomes 'rent' ('rent' can be a synonym of 'lease').
'incorporating' is an insertion indicator.
'half of' means to take half the letters.
'prices' halved is 'pri'.
'rent' enclosing 'pri' is 'REPRINT'.
(Other definitions for reprint that I've seen before include "Publication issued again" , "Reissued publication" , "Make new edition" , "New publication" , "Later impression of a book" .)
