Promotions are discounts applied to a particular item in an order. Customer discount however gives a discount to the order's total amount, instead of particular items.
Once you created a promotion in the management console, it's time to apply it at the POS register.
To apply a promotion discount at the POS register:
Open an order at the POS register.
Add items listed in the promotions created earlier.
Click Promotions at the top right.
Select a promotion you need to apply and click ＋ next to it.
To cancel the promotion, click — next to the promotion.
Now you can close the order by paying it or keep it open for further requests.
