We would like to give a discount to our customers who order through weborder / QR code. At the moment its possible to use a giftcard, but only as partial payment. How we think it should work: Create discount coupons in the backoffice, each coupon has a value. For example Winter 20 gives a discount of 20 euro and Winter 40 gives a discount of 40 euro. When the client goes to the checkout, he can apply a discount code and this amount will be substracted.
