Hi Maria62 -
You can take a tour of a store to see if that helps answer some of your questions.

Once you look at the store and get into the creation process, it should start to all become clear.
For more techinal questions, visit the Stores section of the FAQ on our Help page.

Let me know if there are questions you still have after that.
