Ignore sales ploy (8)
I believe the answer is:
discount
I believe this is a double definition.
'ignore' is the first definition.
(I know that ignore can be written as discount)
'sales ploy' is the second definition.
(type of sales promotion)
(Other definitions for discount that I've seen before include "Ignore - trade concession" , "Reject as unimportant" , "Deduction granted on payment" , "Ignore - price reduction" , "Reductions as for cash" .)
