Sounds like you’re the one misunderstanding goodwill. Goodwill doesn’t donate to ANY causes. Their ONLY contribution is employing disabled people and providing jobs/training. You can read it on their own website.

Who does Goodwill help? Goodwill serves those with barriers to employment. This includes individuals with disabilities, people with limited work history, those who have experienced corporate downsizing and recipients of government support programs. Goodwill’s services are designed to meet the training and placement needs of the individual. https://www.goodwill.org/faqs/#d7

There well known for paying their disabled employees below minimum wage while paying local store CEOs hundreds of thousands of dollars per year.

So don’t tell me about how the high prices I pay will support charities.
