RadioShack offers the Belkin WeMo WiFi-Enabled Light Switch, model no. F7C030fc, for $24.99. Better yet, add two switches to your cart, and pad your order to over $50 (this AA battery holder is 16 cents) for a final price of $49.98 (excluding padding) with free shipping. That's $32 under the lowest total price we could find for a pair elsewhere, and the best per-unit price we've seen for this switch. (For further comparison, we saw a single switch for $12 less in February.) The light switch allows you to control your lights from anywhere with a wireless or mobile Internet connection via smartphone or tablet.
