After the CS300 went on clearance on Adorama for $30 + Free shipping I have been eying on CS400 for a while and never find anything under $80.
So I am gonna call this a killer deal for about $53.xx with Tax and Free Shipping.
Research shows last time it was at this price from Microcenter In-Store only in August 2016.
