When on a budget go to the Goodwill of a higher income community than your own.
Goodwills are more or less a reflection of where they are located, meaning buying from a Goodwill near you is like going to a local yard sale. Where as going elsewhere can be a treasure trove. The more expensive the area the more stuff you’ll find; often people of certain wealth do not want to be seen shopping at Goodwill and will only drop items off.
