If you missed this deal a couple weeks ago, then you're in luck. Today, ebay Daily Deals has the international Galaxy Note II available for a second time. For round two, the price has dropped slightly lower to $579 for the unlocked phone. More specifically, this is for the white, 16GB model.
Again, while the retail price of this phone is around $800, you can still find it online for $660 on a normal day.
