I've had kind of similar things before with DoorDash or UberEats. They'll show I have a discount or some amount off ($5 usually), and then only once I'm ready to actually submit my order the full fine print shows up that I needed to have a subtotal of $30, $40, or whatever. Maybe that's fine for a family but for one person it stinks to think "oh cool I've got a discount" and I waste my time thumbing through restaurants and putting together an order only for it to not be worth it.
