Is this a good place to donate queen and king sheets in good condition? Or should I send to goodwill

I would call them first.

While we do receive donations, we recommend Manna for Donations such as these since we don't have a huge amount of storage. Thank you for partnering with us and thinking of us.

Yes, helps people who are in need. Goodwill is for profit.

Yes..they give it to people in need..goodwill sells it
