I just brought animal crossing lets go to the city on wii and was wondering on how to upgrade his shop because I only have Nook's Cranny and it is really bugging me. On my nintendo DS his shop upgraded as soon as I payed off my first mortage.
u need a number of points on his system to upgrade. so u need about 200 to upgrade to the next one from nook's cranny. u also need somebody from another town, to buy something from nook's
