So one of our very good friends is a millionaire and refuses to listen to the words no. He loves to by things for other people. He insists on buying us expensive gifts and helping us pay for different parts of our wedding. As recent college graduates we don't have tons of money so we obviously can't buy him lavish gifts in return. We appreciate his generosity more than words can explain but we cannot figure out how to let him know. We have sent him thank you cards, gotten him small gifts and always thank him in person. Does anyone have any suggestions so that he knows how much we appreciate him as a friend?
Edit: He is in the bridal party
