Best Buy can already send Geek Squad and Magnolia to your home when you need a fix or some help setting up a new TV. But what if everything is running fine, and you'd just like to improve your tech? The retailer thinks it can help there, too. It's piloting a free in-home consultation service where staff will offer advice about your tech goals (such as home automation or multi-room audio), answer questions and send a customized plan. While you'll undoubtedly be pointed to Best Buy to purchase any missing pieces of the puzzle, there won't be an obligation to buy anything -- you can walk away when it's all done.
