why is this? your insurance change?
The price went up because of the agreement inside Obamacare that states that Insurance companies cannot price-hike after XYZ date (I want to say it sometime in 2014, I don't remember off-hand).
If someone told you that and then left a huge gaping opportunity for you to price-hike before that point in time, what would you do (especially if you were the same insurance companies hiking prices and illegally not covering customers while lobbying for bills that crush your competition)?
