Price Issues
If any product is charged at a higher price than stated on the current shelf ticket/label and the transaction has been completed the following will apply:
Single product: Countdown will refund the price paid and the customer may keep the product free of charge.
Multiple of the same product: Countdown will refund the first product and the customer may keep this first product free of charge. A refund will also be given for the difference between the current shelf price and the charged price for the balance of the products.
If a checkout operator error has occurred during the transaction, only the difference between the correct price and incorrect price will be refunded. Examples of errors are:
Incorrect product identified by operator,
Multiple scanning,
Processing a different product to the one being purchased e.g. sauce mix instead of gravy mix,
Keying the wrong price or multiple price e.g. 30 instead of 3,
Reduced to clear label did not scan
