Poshmark seeks to deliver a simple and fair fee structure that is universal to all of our sellers - thus, we cannot extend fee discounts below our standard 20% commission.
For sellers who may be looking to participate in offers, but do not currently have any additional margin to spare for offer discounts, we recommend raising your listing price slightly so that you can provide an offer discount (e.g., 10% Offer to Liker) to buyers. We typically see higher conversion rate and sales when sellers align their pricing to allow for offers.
