Deciding how much to charge for your product / service can be a daunting task.  You don't want to get it so high it slows sales, nor do you want to leave anything on the table.  In many cases price is driven by a supply and demand scenario.  If there's very little supply and high demand, the price rises accordingly (and vice-versa.)  There's also the need model.  Camp trailers sell for what they sell for — usually.  But after Katrina, when the government was buying camp trailers from anyone who had them (to help provide housing for the displaced people in Louisiana and Mississippi,) the price jumped dramatically.

That brings us to one of my dad's favorite sayings:  “When you're in the woods, you pay woods prices.  If you bought it in town and brought it with you, you paid the in-town price.  When you have to buy it from someone in the woods, that's an altogether different price.”  We've all forgotten something and had to pay woods prices, at some point, somewhere.  You tell the clerk, “I could get this in town for 10% of what you're asking here!”  He replies, “Fine.  Go back to town and get some.  But if you want it here, this is the price.”

It's important to note that woods prices are only valid in the woods.  I've see some people trying to charge woods prices in the city.  They don't last long.  If you live “in the woods,” or have a product / service that is scarce enough or rare enough to justify woods prices, you can make a killing.  Just know that it won't be long before others see how much you're making and start to compete with you.  Eventually the woods prices days will be over.  Enjoy it while you can.
