I use this example a lot because it sorta floored me when it happened. This was the second year of Obamacare and the wife and I decided to not enroll and stick funds back just in case. I need a CT and so I started shopping around. The least I found was a hair over $400.00 cash price so that's where I went. When I was paying they gave me a receipt where one amount on it was over $1600. I asked the cashier about it and was told that's what they would have billed insurance had I had it. And, if I had insurance they would have wanted all the $1600 if my deductible hadn't been reached. Yes, posted prices would have helped in that situation.
