I use a HSA through my employer, getting a lot of tax-advantaged healthcare each year and relatively low premiums at the cost of a deductible that is high for an employer health plan but not especially high for anyone on an independent market.
This plan works out, considering taxes, employer contributions and etc to cost roughly 5000/year in post-tax dollars and I'm getting about 5000/year in actual healthcare (two middle-aged people with ongoing medical conditions. My out of pocket max would put me at maybe 2k more if I had a bad year, so I'm essentially paying nothing for catastrophic care insurance with no deductible and max 2k out of pocket. HSAs are great if you have a good income and cash flow)
This plan already met Obamacare rules, and the only changes were cosmetic (slight change to shift some care such as chiropractic to X days/year instead of out of pocket maximum and preventative medicine drugs are now free, just like other preventative medicine services) but this year, for the first time, cost actually decreased.
2013 cost for self+spouse: $96.66 per 2 weeks
2014 cost for self+spouse: $93.66 per 2 weeks
I've never seen that number go down. Granted saving $3 per paycheck is only $81/year, and it's pretax money, so think about $50/year or 1% of my total bill.
But it went down. That just feels weird. I've been working here for over 20 years and don't remember EVER seeing the contribution for health insurance drop unless the coverage was worse in some way.
