As one of its daily deals, MidnightBox offers the I-Key Keychain Charger and Sync Cable for iPhone or iPod 2-Pack in Black, White, or Pink for $5.49 plus $3.99 for shipping. That's $4.74 per unit and the lowest total price we could find for a pair of such devices by $7. (We saw a single, similar cable for $4 shipped last winter.) This device is designed to fit on a keychain when not in use. It's compatible with most iPhone and iPod models. Deal ends today.
