Hardwoods are expensive too.
Had some Airmiles converted e-vocuhers, and picked these up from a building center today for $100 Cdn:
4/4 maple x 9 ft;
1"x4"x9ft red oak s4s/fas;
1"x6"x 5ft red oak s4s/fas and
2 bottles of Titebond III (4 oz).
The 4/4 maple (rough lumber) was sold for $20 because it wasn't "in the system."

If I had to pay out of my own pocket, I wouldn't have shopped there. Or should I say I wouldn't be buying the s4s stuff. I usually get my rough lumber (walnut, cherry and maple) at a place that has more competitive prices.
