For some orders (especially first-time orders), a temporary authorization charge may be processed to verify the validity of the credit card. The charges can vary from $1 - $100 depending on the total order value.
Note that this charge is automatically and immediately canceled, but may remain visible as a pending 'authorization charge' for a few business days. Authorization charges are never held for longer than a few seconds and should be removed from your statement within a few days of being processed.
If you do not see a refund or if the transaction is not removed from your statement after a week, please feel free to contact us and we'll be happy to help!
