Purplle.com — I am unable to place an order

I am unable to place an order because an out-of-stock freebie is automatically added to my cart. There is no option to remove the freebie. I have tried removing and re-adding the qualifying product, but the same out-of-stock freebie is automatically added again. Since I have not been able to place the order, I don't have an Order ID to raise an order-related complaint. Please remove/fix the unavailable freebie so I can complete my purchase.
