Duplicate parcel I replaced (7)
I believe the answer is:
replica
'duplicate' is the definition.
(I've seen this before)
'parcel i replaced' is the wordplay.
'replaced' indicates anagramming the letters.
'parcel'+'i'='parceli'
'parceli' with letters rearranged gives 'REPLICA'.
(Other definitions for replica that I've seen before include "I parcel (anag) - reproduction" , "Parcel I used to contain exact copy" , "Parcel I found with exact copy" , "Perfect copy" , "Reproduction, fascsimile" .)
