Available to shoppers or about to arrive (2,5)
I believe the answer is:
in store
'arrive' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'available to shoppers or about' is the wordplay.
I cannot really see how this works, but
'available' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
'to' is found in the answer.
'about' could be 're' ('re' means regarding or about) and 're' is found in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for in store that I've seen before include "within retail site?" , "stocked" , "Awaiting delivery" , "Sort of bakery" , "Waiting" .)
