I've run into this before with More Beer. The website is never up to date with all of the backordered items, so it will let you place an order for something that is not in stock. Then, they don't bother notifying you that they are withholding shipment.Our policy is to hold the entire order until everything is available to ship.
Also, I've had more than one order with missing items. When I called to fix the issues, the customer service reps were less than polite.
The great prices attracted me, but the poor support has forced me to look elsewhere. I now avoid them at all cost.
