Now The Leaky Cauldron site has set up a non-profit-making company to raise enough money to buy the card.
If they succeed, they will publish the words for Potter fans to see around the world.
The Leaky Cauldron started taking donations from Potter fans on 3 December.
If they raise more than needed, they'll give the rest to the charity involved, Book Aid International.
We'll keep you posted on how they do!
