DailySale offers the Acoustic Research Wireless AirPlay Speaker, model no. ARAP50, for $39 with free shipping. That's tied with last week's mention as the lowest total price we've seen. (It's a current price low by $10.) It uses AirPlay signals to transmit audio from Apple devices and computers, and features a 20-watt speaker and USB port.

Note: The countdown timer on the product page does not reflect an actual expiration time and resets daily.
