It's not though is it. It's the equivalent of trying to buy something off Amazon, Amazon then emailing you and saying "ok before we take your money you should know that this is out of stock, we'll try and get it back in stock but it's out of our hands. There will be no refunds if we can't get it back in stock but we will send you a version that still works fine but doesn't contain all the features of the original item, now do you still want to buy?"
