For wood, it’s a bargain! (4)

I believe the answer is:

deal

I believe this is a double definition.

'for wood' is the first definition.
(deal is a kind of wood)

'it's a bargain' is the second definition.
(synonyms)

(Other definitions for deal that I've seen before include "Distribute playing cards" , "Plank of softwood timber" , "bargain > timber" , "A port; a (good) amount" , "understanding" .)

I've seen this clue in the Evening Standard.
