Tonor Direct via Amazon offers its Tonor Wireless Microphone with Mini Receiver for $34.99. Coupon code "AOVTAN2Q" cuts the price to $24.49. With free shipping, that's $11 off and the lowest price we could find, although we saw it for a buck less in our mention from last month. It includes two AA (non-rechargeable) batteries, 150-foot wireless range, and a rechargeable receiver with up to four hours of battery life. Deal ends January 31.
