If you are in the US, and wouldn't mind getting a device that reaching the end of its support life, here's a nice deal. The Galaxy Note 4 has been discounted to $350.
The device on offer is a T-Mobile unit but comes unlocked with 32GB internal memory. Color options include black and white. The listing says $399, but the price comes down to $349 when you apply the GALAXYSALE code at checkout.
For that you get a 5.7" QHD AMOLED screen, a decently capable even by current standards Snapdragon 805 chipset and a 16MP camera. You also get a microSD expansion slot and a removable battery - both of which are increasingly hard to find these days.
There's currently no information on when the offer ends.
