DealExtreme / dx.com is a Hong Kong gadget site with thousands and thousands of China products of all kinds, often at very competitive prices. Every order is free of shipping charges, even if you buy a $1 item. It makes it easy to order and forget. The only downside is the shipping time, which sometimes can be around three to four weeks; some things might arrive earlier, though.
Here are the items I’ve bought for myself and others so far, followed my wish list, or list of items which might be interesting. The order list can be download in CSV form, while the wish list had to be scraped. For what it’s worth, here is a small Python script which does that, plus a bash script for HTML rendering of image links and product descriptions.
The Python script uses WebDriver / Selenium, and install for that goes:
sudo apt-get install python-pip
sudo easy_install selenium
