Summary of new prices (6)
I believe the answer is:
precis
'summary' is the definition.
(I know that precis is a type of summary)
'new prices' is the wordplay.
'new' indicates anagramming the letters.
'prices' is an anagram of 'PRECIS'.
'of' acts as a link.
(Other definitions for precis that I've seen before include "Synopsis, summary" , "Prices for a summary" , "Cripes, what a summary!" , "Abridgment (of text)" , "Summary of the main points" .)
