You have “stuff” you don’t want any longer, but it’s not the kind of item you can donate. What’s more, it’s too good to throw out. I’m thinking of that collection of miniature porcelain teacups you inherited, specialized books that your local library will not accept for the book sale, or a crafting kit you had good intentions of creating something with, but in which you have since lost interest. Your local consignment store won’t accept these items because there’s too limited a market for them.
