The first link is Multishop. A fairly well-known marketplace with a good reputation, I also buy there. There is enough information about it on the Internet.
The second link is Amazon Warriors. It is not often found in reviews, but, as far as I know, it also has a good reputation. It specializes in selling gift cards, so it can be assumed that this site was created by some large corporation for money laundering.
I myself have not tried to make purchases there.
The third link is Underground Market.
In the process of surfing the darknet, I did not come across this site often and mostly in a negative way. Most likely, this is a scammer than a real one.
The fourth link is DeepMarket. One of the most famous scammers on the darknet. You can find a lot of information about it. Of course, there are also positive reviews, which are clearly paid for and fabricated by the owners of this fraudulent business. A lot of crap and lies. Probably every second person has suffered from DeepMarket's machinations. This is 100% fraud.
