Transplantation is consistent with the life preserving traditions of these faiths. However, if you have any doubts, you should discuss them with your spiritual leader. People can make a lot of money selling organs. It is a federal crime to sell organs in the United States.

Donation costs the donor family nothing.
All costs related to the donation are paid for by the donor program or transplant center. However, the family is still responsible for the hospital expenses that were incurred trying to save the donor's life and for funeral expenses. The donation costs passed on to the recipient are too expensive. It's the person with the most money or the most publicity who gets the donation. It's just not fair.
