Ramadan offers: timed discounts and coupons

Set an after-iftar offer, buy 2 get 1, and a limited coupon.

Under Promotions create a fixed price from 8 to 11 pm on desserts, or “Buy X get Y” on drinks.

For a coupon: set a code such as RAMADAN and a maximum number of uses. The cashier presses Coupon and types the code; the system refuses it after the last use.
