We've been over this a billion times. Lowballs are whatever if they're polite. Lowballs are ok if they're actually offers (e.g. hey I don't have that much at the moment but can you maybe go down to xxxxx? if not let me know if you ever do). Low balls are NOT OK when they're demands, curt, and lowballs are not OK when they act like they're doing you a favor. It's obvious that you don't have to accept, but if you sell a lot this becomes the norm, making it really fucking annoying. Sellers already have to go through a whole lot to try and make their items attractive and sellable, the last thing we want is a bunch of assholes acting like it's a blessing that they would even offer you 50% of your asking price, shipped to Australia within the day, regardless of whether or not you have an OBO.
