Happened to me too, on Chrome 35.0.1916.47 beta. I've seen the same issue with other sites using Celery as well.

Sorry about that, I'm on Celery's case about it. hopefully they'll fix it soon enough.

This bug is not really one. At least not in my situation. I'm using Disconnect chrome extension (https://chrome.google.com/webstore/detail/disconnect/jeoacaf...) to block all sorts of tracking. When the website is whitelisted the pre-order screen works. Not tested, but I assume this could also happen with other ad-blockers.
