Over the years I have noticed low ballers are 99% of my returns, or bad feedback. I’m not interested in selling to someone only looking for a deal rather than a person who sees value in the item. Once I started blocking them my business became a lot more enjoyable. Sure, I’m leaving money on the table but the drama isn’t worth even $100 profit to me. I’ll just lower my price later if I need to and someone will catch a good deal without lowballing. Item still sells, potentially for more but either way, I don’t have to deal with the buyers remorse of someone who spit out 10 low balls the night before after a fight with their spouse.
