As one of its daily deals, All4Cellular offers this 3-Foot Charge & Sync USB Data Cable for Apple iPhone / iPod 6-Pack in 10 colors for $3.99 with free shipping. That's $0.67/cable and a buck under the lowest total price we could find for comparable USB cables elsewhere, although last week saw a 7-pack for the same price. This pack includes six 30-pin cables in your choice of color. Deal ends today.
