Price I'm ordered to give a quack doctor (7)
I believe the answer is:
empiric
'a quack doctor' is the definition.
(I've seen this before)
'price i'm ordered' is the wordplay.
'ordered' indicates an anagram.
'price'+'im'='priceim'
'priceim' with letters rearranged gives 'EMPIRIC'.
'to give' is the link.
(Other definitions for empiric that I've seen before include "medical quack" , "Old quack doctor" , "Derived from experiment and observation rather than theory" , "Based on experience" , "working by trial and error" .)
