Is not out and about ahead of you (2,5)
I believe the answer is:
in store
'ahead of you' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'is not out and about' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'and' is a charade indicator (letters next to each other).
'about' becomes 're' (regarding).
'is'+'not'='isnot'
'isnot' is an anagram of 'insto'.
'insto'+'re'='IN-STORE'
Can you help me to learn more?
(Other definitions for in store that I've seen before include "within retail site?" , "Sort of bakery" , "To come" , "Soon to happen" , "where shoppers are found" .)
