Price of oak
What is the going price of oak firewood?
The price of oak and other firewood species is largely variable based upon location and current market conditions.
Other factors that will affect the price are whether the wood is seasoned or green, if you need it cut to a specific uncommon size, and potential delivery costs.
My recommendation is to contact some firewood companies in your area and ask them for a quote to get a better idea. Also, craigslist is another place where you can gauge the price. Keep in mind that with firewood, like most products, you usually get what you pay for. Buying from a reputable firewood dealer is usually the best course of action.
Hope this helps.
