this is a certificate that only validates the full domain name but has no info about the company: http://www.thawte.com/ssl/ssl123-ssl-certificates/index.html
this has also the company name inside the cert: http://www.thawte.com/ssl/web-server-ssl-certificates/index....
and this is the Extended Validation one: http://www.thawte.com/ssl/extended-validation-ssl-certificat...
Tipically the price of this certificate grows from one type to the other and also the required documents/paperwork changes (if you register a simple fqdn certificate many times the procedure is completely automated, if you register a certificate with the company inside, or an EV cert, you must send relevant documentation about your company)
Having said that, I would expect this kind of businesses to have at least a certificate with company details inside, or better an EV cert..
The site seal with a popup that includes the company details is not what me nor the op are referring to.
It says that because it is not an EV SSL certificate. go to amazon if you want to see the same message, but from a verisign (non EV) cert.
