OtiumDirect via Amazon offers its Otium T10 Wireless Bluetooth FM Transmitter Car Kit in Black for $18.59. Coupon code "S8XLGZLW" cuts it to $13.01. Plus, Prime members receive free shipping. That's the lowest price we could find from a US-based seller by $1, although we saw it for a buck less two weeks ago. It features a 1.44" LED display, Bluetooth 3.0, 87.5 to 108MHz FM frequency range, microphone, USB charging port, microSD card slot, 3.5mm auxiliary input, and flexible neck. Deal ends November 30.
