Stocked by the shop now or yet to come (2,5)
I believe the answer is:
in store
'stocked' is the definition.
(I've seen this before)
'shop now or yet to come' is the wordplay.
I cannot quite understand how this works, but
'shop' could be 'store' (synonyms) and 'store' is present in the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'by the' acts as a link.
Can you help me to learn more?
(Other definitions for in store that I've seen before include "Approaching" , "expected to appear" , "at the supermarket" , "where shoppers are found" , "Awaiting delivery" .)
