mwave offers the TRENDnet GREENnet 8-Port Gigabit Ethernet Switch, model no. TEG-S8G, for $19.99 with free shipping. That's tied with our mention from two weeks ago and the lowest total price we could find by $13. This item claims to consume up to 70% less energy than the average switch by powering down Ethernet ports when they are unused or when the connected device is off.
