Two of them have the same cover — the only difference is that one’s a paperback and the other’s a hardcover. The paperback costs $40.35, and the hardcover costs $83.62.

The third one is a Gryffindor House Edition set, which includes extra sections about the Gryffindor house at the beginning and end of each book. That one costs $125.45.

For reference, I’m Korean, and I already own the Korean hardcover edition of the series.
