Good prices for freebooters (7)
I believe the answer is:
pirates
'freebooters' is the definition.
(pirate is a kind of freebooter)
'good prices' is the wordplay.
'good' becomes 'pi' (I've seen this in other clues).
'prices' becomes 'rates' (I've seen this before).
'pi'+'rates'='PIRATES'
'for' is the link.
(Other definitions for pirates that I've seen before include "Buccaneers" , "Copyright infringers" , "Chatters, talks foolishly" , "Plagiarists" , "felons found in craft?" .)
