Run sale without a fuss (7)
I believe the answer is:
ruction
'fuss' is the definition.
(thesaurus)
'run sale without a' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'sale' becomes 'auction' (public sale).
'without' is a deletion indicator.
'auction' with 'a' taken out is 'uction'.
'r'+'uction'='RUCTION'
(Other definitions for ruction that I've seen before include "Disturbance, quarrel" , "Find a disturbance in cut iron" , "Uproar" , "In court (anag.)" , "Racket" .)
