Hi I'm a Brazilian record dealer of Brazilian music soul, funk, jazz, fusion, bossa, psych, progressive and also rare records of US, UK, German, Italian, French artists pressed in Brazil. I would like to put a Set Sale List of my entire catalogue but I saw there's no a bulk upload system to do that. I would need to start a Set Sale List of my records here but I don't know why do that. Is there someone who knows how to put a Set Sale List here? Thanks SUMMERBEAT68
