@ Asker: Context? 06:52 Jul 20, 2019
It really would help if you could confirm what the context is here: retail, or other? Typically, at the checkout, the cashier will check that the money-off coupon is still in date, and usually applies to a product that has been actually purchased; but sometimes, people may try and pass a coupon when they haven't bought the actual product, or will photocopy a coupon and try and use it on several different occasions; the shop cannot necessarily police this sort of abuse. |
