Great score!
I've found that a lot depends on where you buy it. Some "boutique" places will charge a premium for that stuff whereas lumberyards will consider it a lower grade and sell it cheap.
When I remember, I'll sort through the hardwood at the box box stores. Usually around here they carry red oak, maple, poplar, and clear pine.
Prices there are high, a bit above what a hardwood lumber yard will charge for the basic species, but if one digs, you can find maple boards that have spectacular curl or ambrosia. Oak often yields quarter sawn pieces and poplar sometimes shows up some great colors besides the typical green.
