Of course we are all tempted to buy at the best price but even more important is to get the right piece at the agreed condition. No one including myself of course can say he never made a mistake but for buying a watch, there are indeed few golden rules that I always obey with no exception. Buying a great piece at a bargain price from an unknown seller isn’t my cup of tea : « if there is a doubt, no doubt I don’t do the deal ». I prefer to miss an opportunity than loose my money... Everything has a cost and buying a great piece at its price is normal, I don’t try to be smart and even avoid buying at low price unless I know the seller, the history of the watch, and the reason why it is offered to me at this low price.
In this particular case I don’t know the details but feel sorry for the buyer and thank you for the warning.
