Bargain found in Kentish Town? (4)
I believe the answer is:
deal
I believe this clue is a double definition.
'bargain' is the first definition.
(I know that bargain can be written as deal)
'kentish town?' is the second definition.
(Deal is a town in Kent)
'found in' acts as a link.
(Other definitions for deal that I've seen before include "Trade; pine wood" , "Pass around (e.g. cards)" , "Distribute cards or do business" , "Bargain or kind of wood" , "Business arrangement in timber" .)
