I'm interested in finding a few Dutch websites in Holland who sell
cigars online to people in Europe.

Try Cursta-Rey Cigar Shop at http://www.longfillerworld.com/

The Holland Cigar House at http://www.hollandcigarhouse.co.uk/index2.html

Sigarenverkoop at http://www.sigarenverkoop.nl/

Someone can delete my comment with my apologies, I did not realize
only specific researchers could answer. My apologies.

Patsmsg-ga,
No problem.  Official researchers are the only people who can post via
the answer box.  Many comments by non-researchers provide information
that is the equivalent of an "answer".
