Kogan is probably clearing out the Nexus 5 in light of the new Nexus 6. 409$ is for a "bundle", including other products, but even just for the phone I believe this is a good price. I already have one, bought one for a family member.
EDIT: Checked two days ago and Google Play had it out of stock. It's now indeed back in stock. Under the circumstances, if you don't need the extras, like Jorkus has stated, GP is a good option as well.
EDIT 2: SOLD OUT
Tempted. I need to either get a Nexus 6 myself and give my Nexus 5 to my partner or buy a 2nd Nexus 5 for her. I'm not sure what to do!
Anyone else considering the Nexus 6 who is a Nexus 5 owner? I used to say a screen that size is too big but my phone is used so often as a media/internet device that it may be worth it.
