When you land on i.maryruthorganics.com you get a 404 error, not a working website. That alone is reason enough to step back. A legitimate business puts content on its homepage and makes it easy to find out who's behind the operation. This site does neither.
The domain ownership is completely hidden in WHOIS records, which is highly unusual for any commercial website. There's no contact information, no about page, and no evidence the site has ever had a functional presence — the Wayback Machine has no snapshots at all. The privacy policy and terms of service files exist but you can't actually view them when the homepage is broken.
For any kind of online business, especially one with a brand name like Mary Ruth Organics, you'd expect to see a real homepage, contact details, and some kind of web history. This site has none of those. If you're asking whether i.maryruthorganics.com is safe to use, the honest answer is that there's nothing here to use at all. Our advice: avoid it and find the actual business elsewhere.
