LEGO Harry Potter was put on the app store on 5th of January 2012.
There is no such thing as a 'Harry Potter Store'. The only thing close to it are the ones at the Wizarding World of Harry Potter in Orlando and the shop on the Warner Brothers site.
You buy it at a movie store.

Depends which book store it is. Any decent book store will sell Harry Potter books and they will most likely be found in the Children's & Teen's section.

It must be a glitch or its just a nicktropolis problem but tell that in nicktropolis message boards to report it so they can fix it.
The Harry Potter e-books are sold on the Pottermore store which opened in March 2012.
