Look, yeah, I'm just a cookie clicker amateur and I don't really know anything but...
The suggested building Cookie Monster gave me was Alchemy Lab which I need almost an hour to wait, and I really don't think there is a need to wait that long right? The numbers were green and had a PP lower than the rest of the buildings so I should just buy that, buttt it's so expensive and I have to wait for a long time!
