What does "This item can be backordered" mean

If an item reads "This item can be backordered" in our shopping cart, we are absolutely able to manufacture more and we are most likely already working on it! We just don't have any in stock at the moment due to high demand. The worst case lead time will be between 6 to 8 weeks from your date of order. Chances are once ordered we are already manufacturing a new batch of product anyway and your delivery time will be shorter. We do our best to keep all products in stock.
