They could do that, however, it would be rather unethical and could put them in bad standing with their publisher and not able to get subsequent books published by that publisher. Also, although they could do this, they would have to put the time and effort into listing the books, packing them up and sending them off. Depending on how many books you are selling, that could entail considerable effort.
