Sounds simple/obvious, but do you have any kind of inventory management/control in your shopping cart? We had an instance where an item was popular to add to the cart, but the cart wasn't releasing these items correctly after they were added and abandoned. Have you tried adding one to the cart and completing the checkout process since this started happening?
