Time to Save via Amazon offers Prime members the Mohu Bounce WiFi Enhancer with Directional Antenna in Black (router sold separately) for $8.79 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $8.64.) That's a buck under our June mention and the lowest total price we've seen. (It's a current price low by $6.) It's purported to triple the area of your router's wireless coverage.

Note: It's compatible with 802.11a/b/g routers with one or two external antennas. It's not guaranteed to work with 802.11n routers or routers with three or more antennas.
