As one of its daily deals, All4Cellular offers the refurbished AT&T Micro USB Car Charger with USB Port 2-Pack, model no. 03032, for $3.99 with free shipping. That's $1.99 per charger, $1 under last month's refurb mention, and tied with last fall's mention as the lowest total price we've seen. (It's also $14 less than the lowest total price we could find for two new chargers elsewhere.) Deal ends today.
