I think this is about a girl who was in a relationship but she was betrayed so she's trying to forget this other person for good. "Things I loved before Are now for sale" This could mean that the other person is now single and is available for others to take. I like to think it means that the love that she felt for him is now over so she's put that up for sale. I think she secretly still likes him but is telling him to stay far away as she wants to spend forever hating him for the pain he's caused her.
