The scrapbook store is not really a store but a small part of another store, they have just a few scrapbook items in comparison to scrapbook stores back home - and all the scrapbook items can be found all over the World as well, they are just at this one location together.
I leave in a few days again and haven't seen it yet, but my mom visited the pet store and said it's similar to the scrapbook store, just a small part of another store that houses all the same pet stuff you find in other parts of the World in a central location. Nonetheless, I bet you Harley will come up witn several items from there!
THe bath store you are referring to is probably Basin, right? It's a chain store, actually, not Disney exclusive but very cool - lots of soaps, lotions, fizz balls, etc. I like to visit but I'm allergic to the smells so I can't stay long =)
Hope that helps!
