I'm going to have to object to this, unless there's some nuance to your approach to this that accommodates to what I'm about to say. Haggling is indeed a form of leverage, something that reflects a lack of certainty on the value of something, and a way of "playing hard to get". However, in ways whose elaborations can be cited, it's often in response to other leverage. To use an example, if I were looking for a certain product, I might find myself having to consult a big business that pressured, blackmailed, or otherwise killed the competition by unfair means. And this big business might be taking advantage of its monopoly by having a high price tag on its products. So then it's natural to walk in and, in order to cope with an underwhelming result, say "this coffee maker is shit, I'd only pay ten dollars for it"; and it's here you might think of haggling as a form of controlled, honor-enforced rebellion against big business, since here you have a cycle bubbling to the surface involve one side who could otherwise topple the business if too displeased and another side who is incentivized to (to an extent which matches observers' expectations of how the haggling might play out) play a negotiation game to avoid the risk of losing face or business. If you could answer this question in the same format for the same reason, surely (along with what else has been discussed in this conversation), in a situation like this where it becomes a catharsis for something else that shouldn't be in one's monetary experience, it would be canon to your code of ethics (that you use as a code of honor for yourself and as a TOS for your groups and functions) to take the classic West Asian view on haggling and treat it as a duty (while providing the opposite view when going in under fair circumstances), right?
