There’s a refine button at top of you click that you can click on sold listings will give you a better idea of what stuff sells for...I mostly deal with electronics a lot of testing required... my favorite items are old Nintendo games they sell very well..broken cell phones with shattered screens sell good if newer and you can normally find cheap...as far as chargebacks I don’t get many... maybe 10-20 returns a year and that’s selling an average of 50 items per week
