Ignore incentive to buy (8)
I believe the answer is:
discount
'ignore' is the definition.
(I know that ignore can be written as discount)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for discount that I've seen before include "Deduction granted on payment" , "Reject as unimportant" , "Disbelieve" , "Ignore - price reduction" , "Reduction in price for conduits" .)
