If you are in a market for Galaxy S8 or Galaxy S8+, then this could be your best chance. For a limited time, Samsung's flagship smartphones are selling for $150 off, and another $150 discount can be added with a qualifying trade-in, such as Galaxy Note5, S5, and newer S-series phones, iPhone SE, 5S and newer iPhones, LG G4 and newer, and Google Pixel or Pixel XL.

This means that the unlocked Galaxy S8 can be yours for $425 and S8+ for $525. If you don't want to trade your device, then the Galaxy S8 is $574.99, while the bigger Galaxy S8+ is $100 more.
