It doesn't matter where you get the books from, I get the same amount either way. Perhaps look for somewhere with cheap shipping so you don't have to pay extra. If you get it from a local store you won't have to pay shipping. Only if you exist in London, England on the 27th of March would you be able to buy a book directly from me (in which case I would actually get some money).
They don't really need money in the Court.
