Ok, so, to upgrade into Super T&T, you have to spend 25k bells in the store total, yes? To upgrade to T.I.Y., you have to spend 50k total. Does this mean that since I spent 25k to upgrade to Super T&T, I only have to spend another 25k to reach the 50k mark? Or do I have to pay a completely separate 50k to upgrade? Also, does ordering items from the catalog count towards the store upgrade funds?
