Sony Action Cam costs: $209 http://www.cambuy.com.au/sony-hdr-as15-full-hd-action-cam-hd…
Outright phone costs: $199 https://www.optus.com.au/shop/prepaidmobile/sony/xperia-go
So at the bottom the "Deals" page is the Sony Xperia Go + Action Cam Plan, but under that there was a "Buy Outright" button for $240 which adds the "Sony Xperia Go Bundle" to your cart. (If you hover your mouse over the picture of the phone and cam in your cart the "Sony Xperia Go Bundle" shows).
So to be sure i asked the live chat person to check. This is part of our conversation:
Optus : Can you please give me the link of that page.
You: https:wwww.optus.com.au/shop/Deals
You: the very bottom left is the Sony Xperia Go + Action Cam plan.
Optus : Yes, I am checking on this.
You: It says below the 'buy now' button "or pay $240 and get the phone outright with a 'buy outright' button
You: thanks
Optus : Thank you fur your patience.
You: I've added to my cart. It has a picture of the phone and cam and when you hover over the picture in the cart it says it a ''Sony Xperia Go Bundle"
Optus : I saw that option
Optus : You can proceed with the order.
Optus : I'll help you getting this outright bundle.
Optus : Are you on Shopping cart?
You: So it includes the Sony Action Cam
You:???
Optus : Yes, it has both Sony Xperia go handset + action cam
You: for $240
Optus : Yes.
You: thanks for your help
I don't know if the phone is locked to optus or any other info. Have fun
