As one of its daily deals, All4Cellular offers the 5-Foot 3.5mm Male-to-Male Auxiliary Cable 2-Pack for $1.99 with free shipping. At $1 per unit, that's tied with our February mention and the lowest total price we could find by $3. (For further comparison, we saw a 4-pack for a buck more last week). It's compatible with any audio device with a 3.5mm stereo jack. Deal ends today.
