[Mr. Jeeves]

So then how do I as a merchant price my goods when the value of the commodity used to pay for it fluctuates by the minute?

You could price it in gold weight, understanding that the height of the stack of Federal Reserve paper meant to be an equivalent will vary day by day.

For example, a pair of Nike Air Jordan shoes costs 1/10 ounce of gold. Customers can either give you a 1/10 ounce gold coin, or use an exchange machine at the counter to figure our how high a stack of paper is required that day.

By the time a Zimbabwe-style trillion dollar note is required to pay for the Air Jordans (probably around May, 2018) you'll be glad your customers are already used to gold weight pricing. :)

But again, if the value of that 1/10th ounce gold coin could be $160 when I pick out my Air Jordans and drops to $155 by the time I get to the sales counter only to rocket up to $165 by the time I get to my car then have I gotten a good deal or have I been screwed in my purchase?
