New toaster in shop (9)
I believe the answer is:
stationer
'shop' is the definition.
(I've seen this before)
'new toaster in' is the wordplay.
'new' indicates anagramming the letters.
'toaster'+'in'='toasterin'
'toasterin' with letters rearranged gives 'STATIONER'.
(Other definitions for stationer that I've seen before include "has what writer needs" , "Dealer in writing materials" , "Tradesman" , "Seller of writing materials" , "source of writing materials" .)
