Hey, good question!

I'm going to assume you are in the US and you want it unlocked.

You can get dual SIM unlocked on Amazon for as low as $744 in this group - http://amzn.to/1qvDO2O

At BestBuy you get free shipping but they are currently $820 - http://bit.ly/1UKxRet

You said eBay doesn't count, but I still looked and filtered "Buy it now" and found them starting at at $660 - http://ebay.to/1q94O7b



Happy hunting!
