Hi, I am currently developing a promotion/voucher/discount system too.
First, I have to calculate this in the shopping cart and not in the order. Even if the shopping cart is a reflect of a future order, for me they are distinct. I have many parameters in the shopping cart too like the delivery day, etc.. that the order will just copy. I have $order->createFromShoppingCart( $shopping_cart ); So for the promotion, the PromotionTable has a method findDiscounts(ShoppingCart, sfGuardUser) the shopping cart store the discounts and calculate. The order just copy the discounts and the amount of discount. Hope it helps !
