I remember many years ago in NY I saw a good price at Adorama for a camera. So I bought it, took the box home, and all the accessories had been taken out and the box resealed. Then they refused to give me a refund. So as I rule I avoid them. Sending just the small part is pretty harsh, since you will have to send it back.
