How do they seek out the "best place" if they don't have complete information on what it will cost? It would be like buying cars with no price-tags or MRSPs - yes, there will be good/prestigious dealerships with excellent staff who can tell you the technical details about the car that's right for you, but you won't know how much it will cost you until each component manufacturer sends you their separate itemized bills for months after taking possession of the car, and you can't take the car back (5x tires, 2x wipers, 1x engine, dealership charges, factory charges, line-assembly person 30 minutes @union rates, 1x battery, 348x bolts,1x suspension platform, transmission, etc). That is not a free market.

I am sure I could find a better deal on many medical purchases, but the cost to find them is significant. Purchasing the default/readily-available option is often the best bet because of the hours or days required to find a better solution. Spending a few hours to save $100 or a few days to save $1000 is a clear loss to me.
