I was mostly pleased with the order I made for this slab of 8/4 Alder. One problem I did have was, when placing the order, I saw that there was the option of ordering 'knotty' lumber at a reduced price. I chose the Alder that was supposed to not have knots, but when I received it, there were several knots throughout the slab. The Alder was for a guitar body, and I'll have to strategically piece the wings of the guitar to avoid the knotted sections. Otherwise I was very happy with the order, and I will certainly order from Woodworkers Source again.
