I got my email to purchase on 4-22 at 9:55am (registered for it on 4-19 a little after 12pm), paid for it thru paypal and then got a confirmation/receipt email from Samsung 15 minutes later with an order number and total price showing $108.90 (including tax). If you didn't get a confirmation email with an order number then I'm not sure you'll be able to get it but there may be a chance. As far as status, on samsung.com it says processing gift, in the app it says approved but the status shows review in progress.
People also wondering about why it's taking so long, keep in mind there are 50,000 packages that they are trying to get out and the terms of the promotion did say 6-8 weeks. It does seem like folks who did everything thru the app are having faster turn around times, I did my submission and purchase from a computer.
