If a restaurants offers discounts and coupons, there's a chance these same discounts are not available online via the Menufy website. To check which discounts and coupons the restaurant offers, please click the button on the Menufy website called "Online Coupons" or "Quick Deals". If you do not see these buttons, then there's a chance the restaurant does not offer them for online orders, and only offers them in-store.
Please contact the restaurant directly if you have a coupon you'd like to use, but can't find it on the Menufy website. They may still offer you the discount in form of a refund after you have place your order online.
