Wheeled cart (7)
I believe the answer is:
trolley
'wheeled cart' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for trolley that I've seen before include "Collector of shopping" , "American tram or supermarket purchases carrier" , "Shopping vehicle" , "Yell rot (anag.)" , "Basket, truck on wheels" .)
