Arteck via Amazon offers its Arteck MFi-Certified 3.3-Foot Lightning to USB Cable for $7.99. Coupon code "AXDBQJV4" cuts it to $6.99. Plus, Prime members receive free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds $6.01.) That's the lowest total price we could find for any MFi-certified cable of this length by a buck, although we saw a 5-foot cable for $2 less last week (since expired).
