So what do you get the couple who has everything? How about a donation to a rhino sanctuary or aid for earthquake victims in New Zealand?
Prince William and Kate Middleton on Wednesday requested charitable gifts instead of wedding presents.
The royal couple selected 26 charities to benefit from a special charity gift fund.
The couple is reportedly determined that their April 29 wedding isn't seen as overly ostentatious when the British economy is hurting.
The charities they have selected - including some based in Canada, Australia and New Zealand - represent a range of issues, from support for army widows to local community foundations and the arts.
The list does not include any charities focused on relief efforts around last week's devastating earthquake and tsunami in Japan.
William and Middleton are "obviously very shocked and saddened by the events in Japan," but the list of charities has been in the works for weeks and is focused on countries the prince has visited, a spokeswoman for his office said.
"They are charities that have a particular resonance with Prince William and Miss Middleton and reflect issues in which the couple have been particularly interested in their lives to date," the palace said in a statement.
