So, does this mean that all the sites listed with "bbb.org" are legit ? This is what I found out:

As far as I know only US and Canada-based companies may get the BBB accreditation.

In North America, bbb provides a trust mark program and dispute resolution services for businesses that have committed to a higher standard of ethics and customer service.

Presently, BBB does not offer these programs to businesses headquartered outside the United States and Canada.
