My sister has just started the Urbz: Sims in the City for her DS. She asked me recenlty how to buy things from the catalog, and i have been through it all, and still cant work it out, i can select the item i want, but we cannot buy it, we have over double the needed money, so thats not an issue, what buttons do we need to press to buy it? If i search for "catalog" with the Urbz or anything alike in google i get results for buying the game, so does anyone have an idea for me? It would make my life alot easier, thanks.
