Hm, this is a curious one. We're sorry you're having this issue. Based on what we can see, the mobile app is currently up and running. When you hit 'checkout', it should take you to a page that asks for your email, shipping address, shipping method, and payment method. If you continue to have this issue, we encourage you to call our Sale and Customer Service team at 1-800-426-4840 and see if they can help you place the order. We apologize for the inconvenience.
Hopefully this helps, thanks!
