All4Cellular offers the refurbished AT&T Zero USB Travel Charger Kit for iPhone, iPad, and iPod 2-Pack for $4.95 with free shipping. That's $2.48 per kit and $3 under the lowest total price we could find for two new units sold elsewhere. (For further comparison, we saw a single new unit for a buck less in September.) Each kit includes a charge/sync cable compatible with Apple iPhones, iPads, and most iPods. (See "compatibility" at the bottom of the product page to view all supported models.) Deal ends January 1. A 90-day All4Cellular warranty is provided.
