Whoa! Dude must have had some nice shelves!!! My current level of woodworking is cabinets made with biscuits. No, not the kind Grandma baked. A biscuit joiner is about the simplest, fastest way to make a strong joint without generating plumes of sawdust. I've done Dados with a tablesaw and Mortise and Tenon Joints with a router and it's a *tremendous* amount of cleanup afterwards.
Expensive wood:
One of the laws of supply and demand is that if you price something too high, people won't buy it. In order to help the price of wood come down to realistic levels, people need to say NO to the price. During the pandemic a 4'x8' sheet of 3/8 plywood was {gasp} $55 at Lowes. Needless to say usage dropped to zero-ish. A couple months ago this was around $25ish. I check from time to time to see if insanity has been replaced with wisdom. Looks like wisdom won, this was about the pre-pandemic price..... btw, I am personally boycotting steak for the same reason. Hamburgers are good, and fairly reasonably priced.
