We had SEVERAL returns within a months time where the buyers returned an empty envelope or toys/notebooks when a mechanics tool was what was purchased. I had filed a Safe T Claim on 2 orders where empty small envelopes were returned when the customer purchased a filter drier that was in a larger size box. 2 claims same product, same issue(empty envelope) one Safe T Claim was granted the other was denied.. Amazon telling me to charge a restocking fee but Amazon already refunded the customer
