The I Do Foundation is a non-profit organization that helps couples bring a charitable focus to their weddings. When couples register their wedding through the I Do website, www.idofoundation.org, they select the organization they wish to support.

To support CDF the couple indicates Celiac Disease Foundation.

The couple then generates donations in several ways – through honeymoon purchases, by making donations in place of wedding favors, or by registering for gifts that raise donations.
