Just seen this article on Born to Learn and thought I'd share it you lot in case it would benefit someone:

In short, you can get 6 months free MOOC's courses purely on Azure. The courses look like a variety of slides, videos, labs and quizzes, and on completion of the course you get a certificate to say you've done that particular study.
Also, you can get 1x MS voucher for $99 including a free retake valid for 3 months, 3x vouchers + retake valid for 6 months.. but they're only valid for a variety of the Azure MS exams, you'd have to check the small print for what they cover.
The offer to purchase/subscribe for free training is here:
