Look what I just found at an Australia Post office in the city!
I was stoked! I was able to pick up a copy for my Zumba buddy who's just bought her first house that's too far away and on the wrong train line for her to keep doing Zumba with me after she moves. So her housewarming gift is sorted and it was only $99.99! I would pay that five times over to give someone else the benefits that I've gotten over the last eight weeks.
Anyway, just thought I'd share if anyone else was interested in picking themselves up a copy, I thought you could only buy it over the phone or online but I stand corrected!
