Update: The deal is back, this time from a different seller buydig.
New top-of-the line smartphones naturally come down in price over time, but the Galaxy S4 has shown a remarkable tendency to go on sale early and often. This time it's on eBay for $575, which is $25 less than last time. Not bad for a device that usually sells for nearly $700 unlocked.
This is the unlocked 16GB version of the device, meaning no LTE.
