You can also do 2 people and 4 exam vouchers for $11000.
Microsoft is subsidising DDLS due to corona, so they are running a deal allowing you to book unlimited courses until the end of the year (mostly online, some are in person depending on your city). A week long course usually runs 4-5k with these guys, and the training quality is A+ IMHO.
If you're in the IT world you'll know Microsoft certs aren't cheap. This deal allowed me to get 4 week long courses and a 1 day one slotted in before Christmas. That's a hell of a lot of PD.
Hope this helps someone :)
