Organise sale of drinks (4)
I believe the answer is:
ales
'drinks' is the definition.
(ale is a kind of drink)
'organise sale' is the wordplay.
'organise' indicates anagramming the letters.
'sale' is an anagram of 'ALES'.
'of' is the link.
(Other definitions for ales that I've seen before include "Types of beer" , "Alcoholic drinks" , "A sale of beers" , "What might be delivered by pumps" .)
