When you order brand cards from AliExpress and JoyBuy you're usually safe. I ordered several at quite nice prices. These big sites hate fake products because it gives them a bad name and they want to do business worldwide. I know JoyBuy has daily/weekly offers that are quite spectacular sometimes. You have to be quick though. I bought several DAPs that way for super low prices. Always keep in mind: if something looks to be too good to be true it usually is. Especially from small sellers.
