Very poor almost non existence customer service. Many Many forced cancelations because many sellers do not ship the items they sell and no way to rate their performance once mercari cancels the order as to warn other buyers about an individual. Constantly Hounded for filling out a W9 saying my sales are already over $600 (required after $600 in sales during a year) when my sales in fact are only about $200 for 2022. No answer when email support.
