Band grabbing time in store (5)
I believe the answer is:
stash
'store' is the definition.
(stash is a kind of store)
'band grabbing time' is the wordplay.
'band' becomes 'sash' (a band of material).
'grabbing' indicates putting letters inside.
'time' becomes 't' (abbreviation).
'sash' placed around 't' is 'STASH'.
'in' acts as a link.
(Other definitions for stash that I've seen before include "Treasure trove" , "Hide in a secret place" , "Secret store of valuables" , "(Hidden store of) drugs" , "Stow; secret store" .)
