Buying Graphic Cards on Alibaba

I was looking to start getting into mining. I’ve done a little bit of gaming and research at least into good/profitable cards but I’m still new. I saw Alibaba seemed to sell rtx 3080 between 200-350 here:

as well as 3090 for $600 here:

Can anyone tell me if they know if these are legit? From what I’ve seen they would be considered good deals but they seem a little too good to be true.

On alibaba, vendors tend to put really low prices, when you inquire and send them a message you’ll get a real price from them. Don’t buy from a new vendor unless you go through alibaba trade assurance. If they direct you away from that dont buy.

Okay thanks! If I buy I’ll be sure to follow your advice.
