Lightning cable - $3.50 shipped ($0.75 + $2.75 shipping) after code on Amazon.com
When you use code LTNGWHTE, it comes out to $0.75 plus S&H. For $3.50 shipped with good reviews, seems like a decent/warm deal. It’s also 4 feet in length, which is longer than Apple’s original.
Doesn’t work work with Prime/FSSS, so you have to pick the $9.70 + $2.75 option.
