I agree with all the above: there is no reason for a company to mislead customers about shipping and waiting times. If it is going to take too long for them to get around to fulfilling the order (remember, these cases are all handmade-to-order), then they should offer the customer a refund or ask them to be more patient.
That's exactly the challenge faced by small design studios. If they can only make so many cases in one day, then that's that many they can make. A sudden spike in orders because of a press article or a good review, ironically, can create a problem because they can't keep up with demand, which results in a backlog. Other factors like material supply problems or craftsmen taking sick days will only compound the issue.
