This assumes you are in good health and don't take a slew of drugs to get through the day. If you have a history of breast cancer or spine surgery, or ....you get the idea...kiss that $340/month goodbye. Put a 2 in front of it and wait for it to change to a 3 once you have your first claim.
Quote from Vinny1:
You can get a lower price in NY than $1,300/month. Check out www.ehealthinsurance.com
I saw a quote in Manhattan for a family of three for $340/month, which was the cheapest with Empire Blue Cross Blue Shield.
