There are also real humans who help get people enrolled into Obamacare. So if the net isn't your thing. Locate the wayfinder in your area. Community Action in Skagit County is a place where you can drop in and see a real person who will help you get squared away. I am sure they would know of other places, possibly in your area.

Hope that helps...Good luck
