What everyone else in your area is getting has nothing to do with pricing a product.
Redprospector had a very good post (need to go back and give his some rep love).
I'm going to take a slight quibble with how he phrased that first line, though.
A few years back I was doing some work in the nicest manufacturing plant I've been in -- and on the wall in their finance department was a sign, "Price is not related to cost."
There's a lot of folks who do firewood who start off with just their cash costs and add a little bit to it to come up with a cost. As MN & Red said, you're not getting ahead doing that.
You need to understand your costs for certain.
Pricing comes from both value you provide customers, and constraints in your market.
Firewood tends to be driven by price restraints from folks selling it for way less then the value of the product -- we're at about 1/3rd the price per BTU compared to fossil fuels right now.
Look at Oil, Propane, and Natural Gas for contrast -- there may be minor pricing differences or short term spikes for one or the other, but over time they all track each other closely in price-per-BTU.
They realize even if their costs don't change, the value to their customers does and they change their prices to take advantage.
Meanwhile, oil can double in price and firewood barely moves in price because there's so many beer money producers out there figuring price not based on value to the customer, but based on cost plus a little.
And they don't even figure out cost as what an on-going business needs, just what they need to buy toys or beer. Since fossil fuel (gas, oil, etc) is a relatively small part of the cost, fuel spikes don't drive up cost per cord proportionally.
There's other folks who honestly feel guilty about charging by value and not simply taking their cost and tacking on some presumed fair level of profit (well, if it costs me $1 to produce, I'll charge $1.20...). They leave fair money on the table when the alternatives to the customer all cost $3. You could charge $2 and still provide tremendous value to the customer, and make enough profits to re-invest in your own business.
That's creating a situation that wood is an enormous bargain right now and darn challenging to make a decent profit.
