We were under the impression when we bought the 19 books that the monies went directly to the zoo, whether it be by the people who won it or whether it be by you. That is why we bought them and the only reason we bought them.
We would never have bought the last of the books 2 days later if we had known the rules had changed and the money was going to be held and not donated. The first event and the second event threads clearly did not state they had to be sold on the first night, just that they had to be ALL sold. At the time, we were about to make a direct donation to the zoo, but decided our timing was such that we would donate via the books instead.
Since we did win first and third place, we feel we should have a say and we want that money donated to the zoo either by you, us, or a third party.
