Where on earth did they get $250 for a cord of wood? Unless you're buying them 10-13 logger's cords at a time, then cutting and splitting it yourself, a cord of oak around where I live (which is not at all far from oak trees) is in the $450-550 range.

You can maybe push it down to $300/cord if you know a guy, but then you're not getting properly seasoned stuff, you're getting stuff recently cut from a dead tree left standing for a few years.

Those prices are just generic prices that you fill out with current prices. I have no idea on the validity of any of the prices filled in by default there, but I assume it is prices that whoever made the site many years ago had in their area.

Even the coal price is super outdated. If you get a reaaaaaaly awesome deal, a ton of anthracite is at minimum $350 a ton now. Those are like 2010 prices.

Coalpail is a really handy site. They've got all the hookups on the cheap coal distributors. The guy I buy from isn't listed, you just call him and ask for an appointment to meet him at his coal shed.
