Since estimated shipping time is 3-5 weeks than the time it would likely take to receive a shipping confirmation would be 2-4 weeks since it probably would take 5 business days to receive it from the time it's shipped.
Seriously? It's a confirmation email to let you know your case will ship WEEKS from now. Do you really need to know that badly when the stupid email will arrive in your inbox??? How will the confirmation email change your life?
C'mon people. There's a friggin thread about every speck of minutiae surrounding this case business. People are being ridonkulous. If you're really so desperate for a case, go out and buy a damn case and stop obessessing over which nostril Steve Jobs might breath out of next. If you're desperate for something for free (which is what I suspect), then go to your local cheese shop and get some samples.
