Oddly spoiled, so disposed of (4)
I believe the answer is:
sold
'disposed of' is the definition.
(I've seen this before)
'oddly spoiled' is the wordplay.
'oddly' means one should take alternating letters.
The alternating letters of 'spoiled' are 'SOLD'.
'so' is the link.
(Other definitions for sold that I've seen before include "Disposed of for money" , "Flogged" , "Vended" , "Traded" , "Betrayed for money" .)
