Are you honestly saying you've never gone into a store or market or anything of the such and asked for a better price than what's on the price tag? There are places in the world where not trying to ask for a better price is the default. I remember when I was a kid and visited Hong Kong .. the ONLY recommendation there is never pay what's on the price tag .. lol .. but you're
always allowed to.
You are wrongly mixing two very different and VERY SEPARATE elements of this situation:
#1)
@Keith negotiating for a lower price outside the context of the "Make Offer". (Seller refuses to go below the "asking price".
#2)
@Keith agrees to CURRENT and EXISTING asking price open to all.
There is NOTHING in any way that relates #1 to #2. You might want to think there is because it seems like they go together because it's the same person. But the ultimate question is .. what if
@Keith had tried to haggle for a lower price .. then someone else came in and said "sold" at $10k? THAT is the real question .. because if the answer is yes to "anybody but
@Keith", then that is actually discrimination, and there are actually laws in many places against that.
So ultimately #1 has
ZERO relevance here both legally and morally/ethically.
However .. as I mentioned .. both things are completely separate. That still leaves #2 .. where we need to assess if indeed "Asking $10" in the equivalent to a legally binding BIN? The answer to that specifically, is less clear. In fact, a few posts up I gave a pretty good reason why I don't think it is "technically" (however I would argue it might morally be, but that's not the ultimate question .. see my earlier posts for specifics).
