Indulge cost with points (6)
I believe the answer is:
cosset
'indulge' is the definition.
('cosset' can be a synonym of 'indulge')
'cost with points' is the wordplay.
'with' indicates putting letters inside.
'points' becomes 'se'.
'cost' placed around 'se' is 'COSSET'.
(Other definitions for cosset that I've seen before include "Care for and protect" , "Indulge - pamper" , "Protect overindulgently" , "Treat overindulgently" , "Pamper and spoil" .)
