Sale is arranged in corridors (6)
I believe the answer is:
aisles
'corridors' is the definition.
(I've seen this in another clue)
'sale is arranged' is the wordplay.
'arranged' indicates an anagram.
'sale'+'is'='saleis'
'saleis' is an anagram of 'AISLES'.
'in' is the link.
(Other definitions for aisles that I've seen before include "Total disorder" , "Church corridors for lassie" , "Passages between rows of seats" , "Passageways between seats" , "Supermarket sections" .)
