Lowballer…don’t be one! A lowballer is someone who offers less than what the seller’s asking price in the comments section of the seller’s post on a buy, sell, trade site. It is best practice to privately message the seller if you are going to offer less than what they are asking. If you are not friends with the seller on Facebook it will most likely go to their inbox under “Message Requests”, so be sure to comment on their sale post that you are sending them a message. That way, they know to look at their message requests to find your message.
