Although the state covers 60 percent of the costs of basic care for children living in foster homes, foster parents must fill a significant gap with their own funding to cover the costs of clothing, school supplies, and extracurricular activities. Treehouse funds academic, social, and recreational programs for children living in foster care, with the goals to help them participate in activities alongside their peers as well as succeed academically.

Treehouse's Little Wishes program helps fund extra costs such as a cap and gown to allow a graduate to attend commencement, or the fees to engage in extracurricular activities such as sports or the school band. With the goal to help kids in foster care start off the school year with confidence, Treehouse would like to cover the costs of school photos so students can trade their school pictures with classmates.

Join G-Team and donate $10 to help children in foster care purchase back-to-school photos to share with their peers. If G-Team members raise $520, then Treehouse can fund school photos for 20 children. Each additional $26 raised will purchase school photos for another child.

Unlike traditional Groupon deals, G-Team campaigns typically don't offer you a "discount" or "savings." So "buyer" beware—when you click "Buy" to donate your time or money to a worthwhile G-Team cause, the only discount you may receive is 100 percent off free, priceless karma. Read more about G-Team.
