All4Cellular via eBay offers this USB Cable and Wall Charger Kit for iPhone / iPod 2-Pack, model no. A1265, for $3.49 with free shipping. That's $7 less than the lowest total price we could find for two kits sold separately elsewhere. (It's also $7 less than our mention of a single unit from April.) This 2-pack includes two wall adapters and two USB connector cables.

Of note, this item is not compatible with any iPad model.
