I've been unable to get a response from Armando, and don't know when my 50% coupon code(for being eCCPT silver) runs out. His original email says May 30, but I had a feeling he may mean April 30th.
Given the launch of the new course, I'd imagine Armando is having a rather busy time at the moment.
The 50% coupon expires May 30th, it gives you a month to get the course.
There appears to be some confusion over this from other sources I've seen, this question has also been asked on the eLearnSecurity student forums, but hasn't been replied to yet.
I received two e-mails, the first specified May 30th as a deadline, the second mentioned no deadline.
