- **Trustpilot** (https://de.trustpilot.com/)
A popular site where users can review lesser known shops and tell others about their experiences.

- **Trusted Shops** (https://www.trustedshops.de/)
Trusted shops is an established german company listing trusted e-commerce shops. You can also search their lists of trusted or fake shops.
If you aren't german / european, maybe there are other regional alternatives for your area.

- **Online Forums**
If a google query doesn't give you the right answers, you can search through some other forums like reddit, if someone else ordered there.

- **Fakespot** (https://www.fakespot.com/)
Gives you an Amazon Addon for analysing user reviews, and might help you sort out sketchy sellers. An additional tip for buying amazon products: Look at all replies, and check if the product got listed multiple times.

Still, *be cautious*! If possible, don't rely on one source of reviews. If you ever bought something from a fake shop it depends on your countries laws if and how you can get your money back by informing your bank, etc.
If a site looks sketchy, unprofessional or odd in other ways, and you can't find any information about it online, it's a sign that it should be avoided if possible.
