Good question. The local Aldi here was selling charging cables the other day: micro-USB and USB-C cables were €2.99, the Lightning version €8.99; Same brand, length, etc.

While sure there's some extra margin on those cables it seems the cost of MFi certification seems to be more than just a penny per cable.

Or they could just be charging iPhone users more. I can go on to Amazon now and buy a lightning cable that works fine for much less.
