Changes in people selling Chinese products to world. It seems Ali Express is not allowing people to sell from them through 3rd party apps as before.

Now, it seems, people need to register for a category of products in China (license for some categories), which cost over $1000 (deposit of 10,000CNY or 30,000CNY seem most common), so the online store can dropship from China. It seems you can still dropship from another country.

Also talk of 'wire transfer' for cash. Because PayPal has a high fee.
