Dell Home offers the Dell 2.1-Channel Wireless Speaker System, model no. AC411, bundled with a $25 Dell eGift Card for $69.99 with free shipping. (The gift card will appear automatically in-cart, and will be sent via email 10 to 20 days after purchase.) Assuming you use the gift card, that's $27 below our mention from April and the lowest total price we could find by $29. This speaker system comes with two 6.5-watt speakers and a 20-watt subwoofer and features Bluetooth 3.0 connectivity. Deal ends August 14.
There's a less expensive way, and then there's the way that works for you. The two may not be the same.
