Dear Peter.  Thanks for the Friday night update.  

If I understand this correctly, once you have cast a customers orders and processed them, they can then order a further £50 worth of metal goodies?  The cart remains open?  If so, then that is great news - service is getting faster and our lead mountains will, once again, reach for the sky!  I don't know about anyone else, but I always find that one nano second after ordering, I remember that I should have ordered an extra ....   So, once my order arrives, I'll just have to put another one in!  Keep safe and carry on casting!  Cheers  Colin the Wargamer
