Same here. We were amazed that they could close in 7 business days. It really helped us secure our new smaller place quickly.

Swore by pocket screws for years until a bookcase leaned like the Tower of Pisa. Had to take it apart and reinforce everything with proper mortise and tenon joints (what a pain). Now I mix methods, like using dados for fixed shelves and screws for adjustable ones. Actually found that a bit of glue in the dado makes it rock solid, even without screws. Still hate sanding the ends of those tenons, though.
