91.67

Are you unhappy with the color of your fecal matter?  You can get gold leaf pills that will make your poop sparkle gold.

 Only $91.67 per pill (actually, $275 for 3 pills since they are only sold in sets of 3).  You can buy them on various websites, though 91.67 is the cheapest I could find, at the New Museum gift shop.

Here is the link to the Citizen's Online page, where they would be selling for $425 each, but they are temporarily unavailable:  http://www.citizen-citizen.com/collections/all/products/gold-pills

I was NOT able to find them on Amazon.
