I was able to order only today with the $50 off motherboard discount. I don't know if it will ship, the confirmation came with this disclaimer.
Important Note: If the item you ordered showed the availability designated as 'Limited availability - May not be in stock at the time of order. No backorders.' and it is still in stock, your order should be shipped within the timeframe noted above. If, however, the inventory was sold out before your order was processed, you will be notified via email that the product is no longer available. Because of the nature of these products, limited availability items are not backordered.
In other words, yes, you ordered it, but we can cancel it. Since with the motherboard we are over $100 off Newegg's price, it is worth the effort to try.
I will let you know what happens.
