Your state's new online Marketplace, also called an Exchange, was created mostly for people without insurance from an employer. But anyone can use it to check out their options. The Marketplace aims to make it easy to compare health plans -- sort of like an online travel site for booking tickets.
As long as you live in the U.S., are a citizen, and aren't in jail, starting Oct. 1, 2013, you can buy a policy on the Marketplace. The insurance starts Jan. 1, 2014.
