Some of the supplies to restock the shop (5)
I believe the answer is:
store
'shop' is the definition.
(I know that shop can be written as store)
'some of the supplies to restock' is the wordplay.
'some of' indicates the answer is hidden within the clue.
'STORE' can be found hidden inside 'supplies to restock'.
'the' acts as a link.
(Other definitions for store that I've seen before include "Supply available for future use" , "Supermarket" , "Shop; hoard" , "Reserve, shop" , "Large shop; computer memory" .)
