There are many scammers there. But there are also some old school sellers too.

Make sure you do your research with the seller. Talk to them on the phone - don’t just send money. And if you use PayPal don’t use friends and family it it is more difficult to get your money back.

Many here will day never send money. I have not had problems but I spend a lot of time checking out the seller.
