A Non Subscription Fee Adjustment NonSubscriptionFeeAdj is an adjustment made to your account that isn’t related to a subscription fee. It usually covers things like error corrections or mistakes in charges. This adjustment could result in either a reimbursement to you or a charge back to Amazon for not applying the correct fees. If you're unsure about the details of the adjustment, you can check the payments page in Seller Central or contact Seller Support for clarification.
