Saw this in there fine print below:
Q: Why is an item priced at $9999.99?
A: Because we do not inventory our items, we rely on our suppliers to keep their inventory up to date. When we are notified that an item is very low or completely out of stock, we update our price to $9999.99 to prevent someone from paying for it. Once the item is back in stock, the price will return to normal, or if it is out of stock for good, the item will be removed.
