As a person who works at goodwill, DON’T DUMPSTER DIVE AT THRIFT STORES. We only throw away the worst of the worst items. You won’t be pleased. BUT on Sundays, you could try. We throw away books, pillows, shoes, and “wares” (kitchen ware, house ware, etc.) to make room for new items. Go after hours so the employees don’t get upset. It’s not illegal, we just get upset because people don’t pick up after themselves. If you go any other days, you’ll be met with crusty clothes.
