I don't have any experience with them. You might try a message through their Facebook page if you use that outlet. My interpretation of their website text is you might not hear anything until June 14th.
"The list is now updated. You can place orders beginning at midnight EST on June 14. Orders that arrive sooner will go to the end of the line...And if you'd like a grab bag of unlabeled but beautiful iris, let me know...There's no button to push for this option yet, so if you're interested you'll need to shoot me an email (use the contact link at the top of this page), but........wait until the 14th please."
