I was eventually able to find a post on Uservoice that confirmed there was a discount on Microsoft exams if taken at MSIgnite. Pick the exam and register in the normal way, but when selecting the test center, choose Orlando, FL and then select the Ignite center. This will then give you a 50% discount on the exam that will show at the bottom of the invoice.
All the MSIgnite information is scattered all over the place so you really do need to keep an eye out on the forums and twitter to find out whats happening.
I’m not sure what exams I will take this year but would like to get at least one done whilst I am there.
