100% of Net Proceeds (as defined in our Terms) for purchases on Member For a Day goes to Our Change Foundation, a nationally registered 501(c)(3) public charity, who then grants the funds, less fees, to the benefiting organization disclosed on the item page. If the Hammer Price you paid exceeds the fair market value of the item or experience, that difference may be considered tax deductible. Please note that we're not tax experts and can't provide tax advice - consult a tax professional to determine potential deductibility of your purchase.
