Walmart delivered a giant check to Wigs for Kids in St. Clair Shores Friday.
The group asked for a grant of $25,000 and got $90,000 instead.
Wigs for Kids provides free wigs to kids and young adults who are coping with hair loss from various medical conditions and illnesses.
The donation of $90,000 will support 90 children and their families.
Every wig is custom-fitted, and individually cut and styled to help patients feel more comfortable.
