Supplier (8)
I believe the answer is:
purveyor
'supplier' is the definition.
(I know that purveyor is a type of supplier)
This is all the clue.
(Other definitions for purveyor that I've seen before include "Supplier of victuals" , "Supplier of provisions" , "Provider (of goods)" , "Supplier (of food, etc)" , "Retailer" .)
