This sale is great for the people who were after these sets. I would have been very happy too (after all, the first nugget set I bought more then 2 years ago was the deputy chef set, and I was very happy with it). Having them in the UP shop permanently perhaps might be more interesting though. Adds a new dynamic to the game.
