I think it ends up being close to 9% iirc. You can make a draft of a listing, put in your asking price and it will give you an estimate of how much you will net on the reverb app
It’s unfortunate it’s so high. Stuff isn’t moving off forums right now, so resorted to reverb on some stuff. I’d rather hang on to some stuff than take a beating on the price then pay their nonsense on top of it.
Shipping costs have a percentage taken off too. That is to say, at least one of the percentages are calculated from selling price + shipping price, not just selling price.
