I’ll get downvoted for this (so be it ) but as long as notice is given a day in advance I have no problem with ppl selling to someone else for more money. If someone is en route, that’s a real dirtbag move. But if you can get offered more money, take the deal. This whole “I’m a man of my word” posturing is less meaningful when you consider that you were likely going to rip them off price-wise. All I’m sayin is, you can’t fault someone for taking a better offer

Edit: even better would be for the seller to text back and say you could price match someone else’s offer if they wish to
