The LG V20 will welcome a successor at the end of the month, but its still a pretty solid phone. And it can be yours for $350 under the right conditions. First, you need to be in the US.
Second, you need to grab one from NewEgg before Wednesday. Its listed at $375, but you can knock $25 off the price by paying with Masterpass and applying the MPBTS17 code.
This is for the LG V20 US996 model with 64GB storage and Titan Grey paint job (the Silver model is double the price for some reason). Amazon and B&H Photo Video have the same model (with warranty) for $400.
