If you live in MA, you can purchase health insurance using the state exchange over the web. Minimal prices for a family of two are about $550/month (or were last I checked). Prices/availability can only vary based on age/gender/location so you don't have to worry about being denied coverage for a preexisting condition. You can cancel with one-month's notice.
