Goodwill is owned by an individual and is not what it is portrayed to be. Everything is donated and then sold either through their stores or on line. It is like any other business, except they use the system so they can hire at a lower wage.
The Salvation Army, Volunteers of America, and other organizations who receive donated items help a great number of individuals with their proceeds. Not Goodwill, it goes into the pocket of the business owner.
At one time you could find some very nice things at the local Goodwill stores, but not anymore. Most of the stores mainly sell clothing with a scattering of other items. All of the "good stuff" is sold on line where they can get more money for the items.
The clothing prices have reached the place where you can purchase new items, on sale, for close to the same price as they are charging for used items. Occasionally you can find a bargain, but not often.
I would suggest donating to organizations that will use your donated items to help others, instead of donating to Goodwill where it only helps one individual. With other organizations some of the items are placed for sale while other items are free to those in need. They also use their proceeds to help the community and the people within that community who are homeless or struggling for survival.
