Some sales to resume in shops (6)
I believe the answer is:
stores
'shops' is the definition.
(I know this)
'some sales to resume' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'STORES' is hidden within 'sales to resume'.
'in' acts as a link.
(Other definitions for stores that I've seen before include "Accumulates, saves up" , "Puts aside for future use" , "Keeps" , "Lays away for future use" , "Puts away for a tosser" .)
