These 4-packs of MFi-certified Lightning cables are $(removed). That's $(removed) per 3-foot cable – the lowest price by far I've ever seen for MFi-certified cables. (You can get non-MFi certified cables for less but they suck.) I just bought two 4-packs.
UPDATE: Some of the reviewers on Amazon suspect the cables are not MFi certified, and a lot of the reviews were written in exchange for a free or discounted pack of cables. I'll let you know if the 8 cables I ordered are OK.
