edit: just checked Ebay, and yup, there are no legit new copies to be had, except for maybe AT&T or unlocked variants for $400+. There's a very low chance that anyone will be/or has been able to find a new LG V20 for at least a year, and almost certainly not for a reasonable price.
It is a similar situation for numerous other smartphones on the used market, most new copies for sale are actually remanufactured/used that have been repackaged and fraudulently resold as new from somewhere [originally] in China. The fake LG V20 new copies began flooding the market somewhere in the past 1-2 years, and have dominated since, but that practice is typical for smartphones in general.
