Its been "acclimating" in my shop for a year or so, so I don't remember exactly, but it was something like $2.65/bf before straight lining and skip planing.  I go to a regular hardwood lumber yard for it, they have everything.

Here's a few more snaps.  Most of it has some kind of defect like big checks, knots, or even bark, and it's pretty regular wormy maple, mostly.  But being a lower grade it comes with lots of surprises.  I just ordered 200bf with no regard to length or width, whatever they pull off the pile.  Sometimes the project stipulates the wood, sometimes the wood picks the project.
