DealExtreme
The USB cable for my iPhone is starting to break at the point where the USB connector attaches to the wire. I could pay Apple $19 to get a replacement, or I could find a third party reseller and pay $3 + shipping. Or I could go to DealExtreme and get it for the all-in price of under $2.
DealExtreme is an electronics retailer based in Hong Kong that sells a lot of mostly computer-related electronics. They don’t really sell major components or whole computers like a company like Newegg does, but they’re well known for selling gizmos like memory card converters and readers, USB hubs and peripherals, cables, LED flashlights, and so on… which are all made in China by companies you’ve never heard of. Remarkably, they don’t charge for international shipping. This sounds kind of dodgy, and even though I was referred to this site personally by an acquaintance, I still felt the need to do some due diligence on the net to satisfy myself that they were legit. They must need to move a tremendous volume of goods to stay in the black.

I believe shipping is quite cheap in HK :)
I’ve bought plenty of things from Dealextreme, good little site!
