PC desktops and laptops as well as a number of home electronics have had their price marked down or come with bonus gift cards during the Memorial Day sale going on right now at Dell. Some of the best deals are on electronics and TVs, like this LG 49" 4K Smart TV (model: 49UH6030) that drops from $549.99 to $449.99 and comes with a $150 Dell e-gift card. Walmart carries this TV for $30 less, but the included gift card makes this a stronger deal. This TV has a native 4K resolution and 4K up-scaling, built-in WiFi, a 120Hz refresh rate and two HDMI ports. Sales tax is charged in most states.
