Samsung Galaxy S4 i9500 + free bonuses and shipping for $670 from Unique Mobiles
* Bonus C-Tick compliant Charging Adapter
* Bonus Leather Flip Pouch - Store your cards or turn your pouch into a stand to watch your favourite video clips
* Bonus Armband - Secure your S4 to your arm with this high quality arm strap
The same phone from Kogan but without the free bonuses will cost you $658 but the shipping lead time is an estimated 2-3 weeks, rather than Unique's 4 days for express shipping. The best price though for the phone that I could find was from DWI at $652 (shipping included).
Guess the decision to buy from Unique Mobiles comes down to whether or not you need the additional extras.
