Howdy folks, my little lad, seemingly like many is trying to master set Perfect Order. Started easy, packs were on shelves. Finding singles is easy, got over 85%....

So now he is down to needing 3 Reverse Holo's. Where do I find these single little things people either don't advertise, or shops don't keep that stock... So where does one find these last elusive required buggers? It's his birthday next month, I'd love to find these last 3 by then. Any tips appreciated. I'm Sydney based if that changes anything.
