These plugs have a working pass-though so you'll still have access to your outlet.
Brad's Deals Editor Michael,
This TP-LINK HomePlug Gigabit Pass-through Powerline Starter Kit drops from $66.99 to $49.99 when you apply the code EMCRKBE38 in your cart at Newegg. Plus the shipping is free. This is the lowest price we found for one by $10. These kits create a direct connection to your router using your home's existing electrical wiring. They can transfer up to 1,200Mbps and do not require any additional setup outside of plugging in an Ethernet cable. There is no sales tax (except CA, IN, NJ, and TN).
