A back order is what happens when we have completely miscalculated our stock levels and are currently in production to fulfil the back orders. Sorry about that :(
At this point you may be wondering why we don't just disable the option to purchase until we have more stock?
Well we used to do that, and then we would get emails asking why don't we just do back orders and keep the add to cart button active, that way the customer can be guaranteed not to miss out next time we are in stock.
Indeed, these are the dilemmas we deal with, some people say do it like this, others say do it like that. Who is right, who is wrong?
And now here we are, at a mate that is stale (commonly referred to as a stalemate).
We don't like mates that are stale, but sometimes thats just the way the stale mate cookie crumbles (they call me mixmaster metaphors).
