Brad's Deals Editor Michael,
The Marshall Kilburn II Portable Bluetooth Speaker drops from $299.99 to $199.99 with free shipping at Amazon. This is the best price we found by $20. These retro-styled speakers have analog bass and treble knobs that you can use to tune their sound. Along with Bluetooth, they also have a 3.5mm audio input for playing music using an auxiliary cable. Sales tax is charged in most states.
