No promise is set in stone and no deal is closed until the money’s in the bank.
It’s understandable that certain domain deals go south, despite the expectations and promises they were initiated with.
As a domain seller, I am respectful of the occasional ‘change of heart’ by the prospective buyer; unless they already signed a binding agreement, that is.
Genuine situations can be related to an illness, an accident, an unexpected financial loss. If that happens, I expect the other party to explain their hardship; I’m willing to nullify a deal when that occurs.
When you flat out lie about it, however, and you’re later discovered to be lying - particularly after you kissed butt to walk off the deal – then be ready to be outed as a big, fat liar.
An excuse for one such deal, claiming that they were gone camping in upstate New York and without any cellphone signal to respond to emails, all while that same evening they tweeted, is a display of lack of ethics. I despise unethical people and karma sooner or later catches up with those that do it systematically, in personal or professional transactions.
As Mike Mann said in one of his famous ‘MannQuotes’: If you don’t lie, you don’t have to remember what you said.
