I can see both MNGuns & Tomtrees perspective on pine.
It goes for about $75-100/cord here. Maybe $150 on the high side.
Even on that, a quick Searchtempest review of Craigslist for southern New England cities only turns up four ads -- two of them specifically advertising it as camp firewood.
There is a big prejudice in our area against burning pine. Growing up you'd think it was the most dangerous thing on earth for all the people convinced of the danger of a chimney fire from burning it.
I burned it once, other then a surprising pain to split (lots of knots), I didn't mind it.
Business wise, it can be an "opportunity cost" depending on your specific situation.
If you have enough oak to fill all your orders at $225 (I'm pretty sure Tom gets more then that, too), you lose money forgoing an oak delivery to sell someone pine delivered at $100.
Might just be more profitable to put it outside your gate and let it disappear on it's own then take the time to market it, or even put it in buyer's minds that there's a cheaper alternative to the more expensive oak. And you know if you advertise both you'll spend time "educating" customers who ask about the price difference...some will be customers who get it, and others will just be pains in the rear about it. And you'll explain it some, who'll buy the cheap stuff, then ##### about having bought firewood from you that was nothing but pine.
Pine is a really good bargain if you do the math here, assuming $100/cord for pine and $225/cord for red oak.
That works out to $6.66 per million BTUs for pine, and $9 per million BTUs for red oak.
