Looks like a price war going on with this particular router. It had been $270 since 2014, and earlier this month dropped down to $64 and then again to $61 where it is now. The router has many mixed reviews most complaining about it dying within a month, but it does come with 3 year warranty and the issues appear to be with the release stock and less problematic now.
