I have BCBS of Texas. They just went up 18% on mine for a 5000 deductible to $345 per month. They go up almost that much every year. There was a huge increase when I turned 60 too.

I've also check Humana One. About the same price as others. Too bad we can't shop in other states. It would be nice to have Romneycare. Humana does have a great plan, once I get Medicare. Their Humana Advantage plan. About $15 per month.
