Bargain hunter's delight (4)
I believe the answer is:
sale
'bargain hunter's delight' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sale that I've seen before include "Disposal of shop's stock at reduced prices" , "Occasion for buying at reduced prices" , "Retail event - town in Greater Manchester" , "Auction - somewhere in Greater Manchester" , "Period of low prices" .)
