Negative numbers represent returned or refunded products. Customers must follow properly formatted links from your site to ours, select and purchase a product, and accept delivery, for you to be eligible for a commission income. If they refuse delivery for a product for which you have been credited commission income , we will subtract those commissions from your account when we get the product back. We will do the same if a third-party seller refunds a customer for any reason. Remember that customers have several days to return an item after they receive it (see our returns policy, so the record for the dispatched item and the record for its return may not be on the same report).
