The problem with BA delivery is that its slow. Once you order online it gets put in a queue for one of their call center guys to call and place the order. If what you want isn't available, then they have to call you back to confirm and the whole process can take for ever.
What I usually do ( and did today) is look at the menu on BA delivery and then just call myself to place the order.
Oh and by the way, ordered from "Botique de pizzas" after finding it on BA Delivery, could be worse, could be better, wish it were almacen.
