The $10 deducted during eBay credit card authentication is only to verify the validity of the credit card. eBay will not settle this amount with the bank, so there is actually no fee.
For those who have this question, please don’t worry. You can pay attention to the credit card bill sent by the card issuer that month. If there is a charge record for eBay credit card authentication, you can provide it to eBay for further inquiry and verification. Thanks!
