They are just going to have to wait longer or place a bigger order. Likely they will just wait longer. But they knew that before they ordered because of the chart.
Also shipping was free.
Also If I was vendors I would start change place like amazon or newegg more for my cards as they are selling them at almost 2x MSRP.
Also Also launch price of $400 was for reference cards not aftermarket, but $50 for a quite card is a little much, but I'm running 2x5770 and the upgrade will be nice. Even at launch I was planning on spending 410-430 for an aftermarket card.
