A recent goodwill donor might have accidentally given more than they intended to. While going through a bin of donated shoes in Glen Carbon, Illinois, a Goodwill employee discovered $7,500 hidden in a shoe box.

Greater St. Louis Goodwill Spokesman Phyllis Weiss said she suspects that someone was bundling up a relatives items and didn’t look very closely.

"We would love to return the money," she said. "Donors are the lifeblood of the Goodwill Stores and the Goodwill system and we want everyone knows that if they need their property back or if they have a mistake donation we will do everything we can to get it to the rightful owners so they don’t have to worry about donating."

If you think you accidentally left the cash in the shoe box call the Greater St. Louis Goodwill office at (314) 241-3464.
