DealExtream or DX.Com now is a China source for cheap items. Some great deals can be found here if. Much like a dollarstore, you are selective on what you buy. I have purchased things from Flash drives, SD cards, wallets to game controllers. Some of the items are knock off, but they clearly list when they are.
Shipping is free and you get reward points for purchases and reviews of items you have bought.
It's a good go to site for cheap items, and some times great deals. You just need to be selective. They also have a great return system.
