Prince Harry and Meghan Markle are set to returning $9 million worth of wedding gifts. But why? Well, because the Royal Family does not accept gifts
"The fundamental principle governing the acceptance of gifts by Members of The Royal Family is that no gifts, including hospitality or services, should be accepted which would, or might appear to, place the Member of The Royal Family under any obligation to the donor."
The idea is that they don't accept anything that gives them an obligation to that person who gave it to them.
