Goodwill is a FOR PROFIT organization. They pay their workers extremely low wages, allegedly because their workers are handicapped and couldn't get a job otherwise. It still costs $ to get to work, to have lunch, etc. It's quite a racket for the Goodwill company.
I NEVER donate to Goodwill since I found that out. I have bought fabric there because I use it for charity quilts. The one near me has changed managers and is not run well anymore, so I'm not even doing that now.
