If they ordered it yesterday, did it ship yet? Why not just cancel the order?
Well it seems now that MacMall has dropped the price of the old Mini by another $100 today, $539 now. The customer decided to keep the old one on order and is going to call them to get the extra $100 off. They only use it for email, internet, iPhoto and iTunes. They do burn CD's so they did need an optical, that would have been an extra charge with the new one for the external. So instead of $680 for the new one, they'd only be paying $540 to go with last years model. For what they use it for the older model is more than enough.
