FBM – Return Settings

USA marketplace and looking for help on return settings.

Link for reference to the page in question: https://sellercentral.amazon.com/gp/returns/settings (must be logged into your Seller Central)

It seems Amazon automatically deducts returns for all USA marketplaces. So my question is, how do the other settings work?

RMA: Seller or Amazon

Does this just mean that I have to approve the return before Amazon provides them the return label? Is this just for exempt returns?

Labels for Exempt Items: Seller Prepaid or Unpaid Label

Unpaid Label just means the seller has to pay for it and Amazon will not deduct from me? Does this allow the customer to print the label from Amazon to make it easy or do they have to go to a UPS or USPS facility to buy a label?

Return Instructions

What do you typically enter here?

Finally, if I want to charge a 20% restocking fee, where do I set that up? Where do I have to publish that there will be a 20% restocking fee? I really only plan on charging the 20% for open items or customers who abuse the returns by buying and returning frequently.
