Treasures commercial products of mine (6)
I believe the answer is:
adores
'treasures' is the definition.
(I've seen this in another clue)
'commercial products of mine' is the wordplay.
'commercial' becomes 'ad' (abbreviation for advertisement).
'products of mine' becomes 'ores' (a mine might contain ores).
'ad'+'ores'='ADORES'
(Other definitions for adores that I've seen before include "holds dear" , "Worships, venerates" , "Loves intensely" , "Worships as divine" , "Loves; reveres" .)
