All4Cellular offers the refurbished AT&T Zero USB Charger Kit for iPhone, iPad, and iPod 2-Pack for $4.95 with free shipping. That's $2.48 per charger and $15 under the lowest total price we could find for new units in this quantity. (For further comparison, we saw a single refurb unit for pennies less last spring.) It includes charge/sync cables compatible with 30-pin Apple iPhones, iPads, and most iPods. Deal ends September 7.

Note: A 90-day All4Cellular warranty applies.
