Do not buy phones or laptops from advertisements on Facebook that goes to kouyiad.com. I did a bit of digging into the company offering the unbelievable prices for phones/laptops ($100 for a $800 phone, or $160 for a $2,000 Laptop) regretfully after I got scammed and found the site isn't based in the UK but is a fake website run by Chinese scammers.
Websites or advertisements that link to the 3 below websites are fake web pages. The company is a clothing shop in China!
- www.shoppingcustomer.com
- www.High-Spiritshops.com
- www.kouyiad.com
This is how the fraudulent websites look:

So, don't buy and report it to Facebook so they remove it. You would think Facebook, a multi-billion dollar company, would have a team who investigate anyone who wants to advertise on their website is a legitimate trader.
