well by time i get to level 40 the internet company will be like my ice-cream shops now, my "fall back" when I don't have the money for my MTs and Lofts. By upgrading them to 5 (maybe 6) each that'll be plenty of time to get a crap load of money for upgrading my NC to the next level. no? why not upgrade them if its really cheap and takes up time for saving
