How do you react to being undercut?

[Ilmoran]

Anytime I see someone undercutting by 1 gil, it just makes me laugh. Im pretty sure that one gil isn't going to sway someones decision on a 5k item. I often buy the next higer priced item just out of principle. If you're going to undercut... undercut otherwise don't waste my time.

I do the same thing on big ticket items, and for that reason, I never respond to 1 gil undercuts.
