Is the eCommerce.Order.Steps.Confimed the way to change the amount or is there one BeforeSentToGateway method ?
We use Cart v2 on this posta.fo solution.

Is there an equivalent method for order object like the one on orderline SetUnitPrice() ? 

This is my code so far, but it is not working correctly:

public override void OnNotify(string notification, Dynamicweb.Extensibility.NotificationArgs args)
{
    Dynamicweb.Ecom7.Cart.Notifications.OrderIsPassedToCheckoutHandlerArgs handler =
(Dynamicweb.Ecom7.Cart.Notifications.OrderIsPassedToCheckoutHandlerArgs)args;

    Order o = handler.Order;
    string cc = Base.ChkString(o.CustomerCountryCode).ToLower().Trim();
    LogEvent(o, "Country code for order is: " + cc + " in shop: " + o.ShopID);
    if ((cc == "dk" || cc == "fr") && o.ShopID == "SHOP5")
    {
        if (o.PriceBeforeFees.Price < 80)
        {
            foreach (OrderLine ol in o.OrderLines)
            {
                ol.SetUnitPrice(ol.Price.PriceWithoutVAT);
                ol.Save();
                LogEvent(o, "Update product price for " + ol.ProductName + " to " + ol.Price.Price + " (" + ol.Price.PriceWithoutVAT + ")");
            }
            o.UpdateVAT(0.0);
            o.Save();
        }
    }
    handler.Order = o;
    handler.Order.Save();
    LogEvent(o, "Order price is updated to " + o.Price.Price);
    base.OnNotify(notification, handler);
}

private void LogEvent(Order order, string message)
{
    string str2 = string.Format("Order {0}: {1}", order.ID, message);
    LogToFile.Log(str2, "/eCom/CartV2/Events", LogToFile.LogType.ManyEntriesPerFile);
    if (order != null)
    {
        order.DebuggingInfos.Add(new Order.DebuggingInfo(str2));
        order.SaveDebuggingInfos();
    }
}
 

The order vat is not set to zero when order price without fees is under 80 kr.
In my code i have tried (loop of products) to set all product prices to without vat prices. This should be removed if i get Update(0.0) to work.

Dynamicweb.Ecom7.Cart.Notifications.OrderIsPassedToCheckoutHandlerArgs handler =
                (Dynamicweb.Ecom7.Cart.Notifications.OrderIsPassedToCheckoutHandlerArgs)args;

            string cc = Base.ChkString(handler.Order.CustomerCountryCode).ToLower().Trim();

            LogEvent(handler.Order, "Country code for order is: " + cc + " in shop: " + handler.Order.ShopID);
            if ((cc == "dk" || cc == "fr") && handler.Order.ShopID == "SHOP5")
            {
                if (handler.Order.PriceBeforeFees.Price < 80)
                {
                    handler.Order.UpdateVAT(0.0);
                    handler.Order.Save();
                }
            }

            handler.Order.Save();

I have tried to execute sql query (order and orderline objects) for doing the updates, but this does not override the order price, they must be recalculated at a latter stage.

If i read the order log lines there is a line where it updates the price after the OrderIsPassedToCheckoutHandler is called. This is the line:
Order ORDER2194: Order price is updated to 58,6

My order price should be 57,0. How can i change this price to 57,0 ??

AllowOverridePrices setting was the flag i was looking for, thx. The last price update is not called while AllowOverridePrices is set to true.

What is now the best practice to override Order.Price.Price ? sql queries ?
This property is readonly.

Just changing the Order object values in the OrderIsPassedToCheckoutHandler is not enough. The Order object is only modified until the next Order is called or recalculated. I needed to set this code into my OrderTemplateExtender as well. 
Now it works. 

Thanks for inputs. I would like it to be more simple to manage such a simple requirement.
