Attractive reduction at end of sale (4)
I believe the answer is:
cute
'attractive' is the definition.
(I've seen this before)
'reduction at end of sale' is the wordplay.
'reduction' becomes 'cut' (cut is a kind of reduction).
'at end of' suggests the final letters.
The last letter of 'sale' is 'e'.
'cut'+'e'='CUTE'
(Other definitions for cute that I've seen before include "Pretty and attractive" , "Daintily pretty" , "Lovable" , "Small, delightful" , "Clever - attractive" .)
