The Five Stages of Acquisition, according to the Ferengi, are infatuation, justification, appropriation, obsession, and resale.

In 2376, Harry Kim quoted the five stages to B'Elanna Torres when the two were discussing Tom Paris' new "hobby," the salvaged space shuttle Alice. Kim likened Paris' interest in Alice to the Five Stages and told Torres that at that point, she only had to wait for one more stage and Paris would forget about the shuttle. (VOY: "Alice")
