Delayed response to this - because I am actually out riding in Japan, instead of slinging shit on the internet.
To clarify some stuff:
I did not lowball the seller. How can I be lowballing him when I have not even made an offer yet?
And I was not trying to guilt him, either. Just giving honest information on my situation and what is out in the market.
Basically I just told him that I am interested in the bindings but not at his asking price, so whether he could lower the price. No sinister or evil intent here.
