Today only, DailySteals offers this LED Sound Activated T-Shirt in Equalizer, Sunglasses, or Cube styles for $2.99. With $4.99 for shipping, that's $2 under our November mention and tied for the best we've seen for any such sound-activated shirt. (It's also $6 under the lowest total price we could find for a similar shirt elsewhere.) They come in sizes S to XXL, although not all styles are available in all sizes.
