Not a bad price!
Personally, I've gone away from the chargers with built in wires. I now prefer the ones with the USB jacks, so I can use the same charger for different devices (with appropriate USB cables). Here's a pair of chargers for $5.35 shipped:

But beware of the cheaper wall chargers. I've had two different ones that were crap. The prongs that fit into the wall kept falling out! Yeah, pinch one of those out with your fingers, why don't ya? :P But the USB car chargers have always been great (not much to screw up on these).
And these are $0.99 shipped on ebay all day long!

Btw, here's the wired variety for $5.78 (free ship) on ebay.
