I just saw this online—very clever, very shameless.

A jade bracelet worth tens of thousands of dollars is sold for 9.9, with a link to an appraisal agency, and an appraisal fee of 20.
So you pay 29.9 to get a bracelet worth over ten thousand. When you receive the item, you find the bracelet is broken. The bracelet can be returned, but the appraisal fee cannot.
You want the bracelet, but they want the appraisal fee. Yes, the shipped item is broken.
Another guy had a girl in the live stream subtly selling USB drives, claiming everything you want is in the USB for 9.9.
When the customer receives it, it’s just the news broadcast. Out of anger, they want to return it, but the seller sets the return address in some Gala in Xinjiang, and the return fee is 25. The customer gives up.
It’s said they can sell goods worth two to three million a month.
Genius will never go hungry no matter what.
