As one of its daily deals, iTechDeals offers the PowerLine 4.2-amp Dual Hi-Power Wall Charger bundled with a 6-Foot 30-Pin Charge/Sync Cable for iPhone or iPad for $5.99 with free shipping. That's the lowest total price we could find by a buck, although we saw it for a buck less in November. Although it includes a cable for Apple devices, this charger can also support other portable electronics (up to two at a time).

Of note, you can buy two for $9.99 with free shipping. Both deals end today.
