Second-hand photographic equipment trading network

Many photographic equipment trading networks are unreliable. I want to buy a SLR. Because I want to save hundreds of dollars, I ordered a Nikon D90 on an online sales platform next to Gome, Airport Road, Baiyun District, Guangzhou. I was cheated of more than 2000 yuan. Later, I found that many netizens were cheated and there was no way to report it. This network is very cunning. After a period of fraud, the website will change its name. So it costs thousands of dollars to buy equipment. If you make money directly, don't consider it. Don't lose big because of small things.
