Scenario:

Sale Price = $10.00
Starting Price = $1.00

User wins auction with $5.00 bid. Email generated to prompt user to login and checkout/add to cart. Last step to confirm order and the following error gets generated:

Your order could not continue because one of the items you are trying to purchase using the “Buy Now” feature cannot be purchased because it has expired. Please remove the item from your cart to continue. The item is: widget123

Is there a way to turn off "Buy Now" function automatically once auction expires. If I go in and remove the "Buy Now" check mark on the product page and have the user redo checkout, it works fine and an order gets created.
