WiFi range extender $35

Just got a price alert on this D-Link Wireless N300 Range Extender Only $35 with free shipping. Today only, it is a lightning deal and it touched the lowest price ever. So what does this device do? Plugs into an outlet and extends the WiFi you have to areas that the WiFi did bot reach before. Or in other words it makes your internet reach those hard to reach places.
