Yes, that can happen. Sometimes we think your Mac is in a better condition than you think it is and sometimes in a worse condition. It is also possible that defects come to light during the test that you were not aware of. It is therefore possible that the final offer will be higher or lower. When it is higher, we will transfer this amount to you. When it is lower, we make a new offer. You can then choose whether you agree or whether you would prefer us to send the device back.
