Ferengi's Stages of Acquisition (taken from Wikipedia)
Stage 1 - Infatuation: An unreasoning love or attraction … "I want it."
Stage 2 - Justification: Moral excuse used to explain … "I must have it!"
Stage 3 - Appropriation: To take to one's self in exclusion of others … "IT'S MINE AT LAST!"
Stage 4 - Obsession: A compulsive or irrational preoccupation … "Precious!"
Stage 5 - Resale: The action of selling something previously bought … "Make me an offer."
If you are not a Trekkie (someone who watches Star Trek religiously), you probably need some introduction...
The Ferengi is a race of aliens first introduced in Star Trek: The Next Generation as unscrupulous intergalactic traders. Initial opinion of them were very low as they were seen to be utterly without morals and their loyalty can be bought with latinum (a type of precious metal legal tender for intergalactic trades). It wasn't until the spin-off series Star Trek: Deep Space Nine did we get a better understanding of the Ferengi through the character, Quark. who was the proprietor of the station's largest entertainment establishment (casino, watering hole and virtual cat house). Quark had loyalties and loved his kin to the point he MIGHT even consider making a loss to get his friends or relatives out of trouble.
Anyway... the Ferengi are masters of negotiations and have a set of laws that they call the Rules of Acquisitions and of course they come in stages as shown above. Not so different from what most of us humans do actually... but one must always remember the last stage of the 5 stages - what is bought MUST BE SOLD!
