As one of its daily deals, A4C offers the Apple 3-Foot Lightning to USB Cable, model no. MD818ZM/A, for $5.75 with free shipping. (Dealstockcom via eBay has an OEM cable for a few cents more.) That's tied with our mention from three weeks ago as the lowest total price we've seen for an authentic Apple cable. (It's a current low by $1.) Deal ends today.
