Yes, the wife and I use the exchange. We opted for a cheap plan $750 per month (basically catastrophic illness coverage, $4000 max out of pocket) until we turn 65 in a couple of years. YMMVDepending on how some things break I’m somewhere between 3-7 years away from retiring.
Has anyone out there retired before qualifying for Medicare? I guess staying on the spouse’s insurance is one option. What else…buying it off the Exchanges???
