:: shrugs:: I just don't Understand

I got a 'script for an antibiotic today.

Cipro 500 10 pills

Since I don't have prescription coverage, I went to Meijers because they charge:
NOTHING ... FREE.

The were out of stock.

I next went to Walgreens and their charge:
$22.00

I crossed the street, walked into CVS. Their cost:
$11.00

I got in the car (thinking I'll wait until tomorrow and go back to Meijers) and called Kroger.
$4.00

These prices were for brand name, not generic.

I already have experienced the cluster fuck the health care system is in, but could someone please explain this whole med's pricing difference to me?

What IS wrong with a regulation on this (and other medical billing/charges) being put in place vs allowing private businesses obviously in control of their stock holders PROFIT margins? There has to be middle ground somehow, government vs privately run health care.

There is a whole lot of money being wasted made.

Profit is trumping actual health care.
