There's your problem.

I went on vacation yesterday.  I stupidly left my prescription meds on the dining room table.  Oops.

The meds cost me $10 with insurance at Walgreen's.
An online pharmacy sells a thirty-day supply of the same meds for $37.
When I called Walgreen's to replace them, they quoted me a "cash price" of over $500 for the same thirty-day supply of meds.  A three-day supply was $59.

What the hell?

I ended up going to Target and getting two days worth of meds for $22.  That is more than half what the online pharmacy charges for a thirty day supply.

I don't know about you, but I see something very wrong with this picture.
