I am starting to work on the 70-473 exam and normally the exam would cost $165. With my MCT discount it would only be $82.50. However, right now Microsoft has a deeply discounted offer for select Azure exams. With this discount I was able to get not only the exam voucher for the 70-473 exam, but also the Measure Up Practice exam, and a free re-take for only $99. There is an even deeper discount if you are going to take 3 exams. Found out more here.
