The Marketplace fee is currently 9%
This fee is broken down into two parts, a 6% commission paid to Restocks and a 3% credit card processing fee paid to our payment processor. (Currently Stripe)
The commission allows us to pay for overhead costs to run the marketplace, which include servers, hosting and other web related costs. As the cost of operating the marketplace changes, this fee may increase or decrease at any time.
The credit card processing fee is a standard fee all payment processors charge to process transactions. It is unlikely to change in the foreseeable future.
