When it comes to returns on Amazon's Fulfillment by Amazon (FBA) program, sellers are often faced with several costs. For instance, when a customer returns a product, Amazon may charge a return processing fee, especially for items with high return rates. This fee varies by category and is intended to cover the cost of re-inspecting, re-packaging, and restocking the item.

Moreover, regardless of the reason for the return, Amazon will deduct a 20% refund management fee from the original referral fee. For example, if the original referral fee was 10,Amazonwillretain2 as the refund management fee. This applies to both full and partial refunds.

It's important to note that if the return is due to an error made by Amazon, such as a wrong item being shipped, the seller will not be charged any return fees. However, for returns initiated by the customer, such as dissatisfaction with the product, the above-mentioned fees may apply.
