How to buy?

The unknown charge is a bank authorization

When you place an order, we contact the issuing bank to confirm the validity of the payment method. Your bank reserves the funds until the transaction processes or the authorization expires. This reservation appears immediately in your statement, but it isn't an actual charge

If you cancel your order, the authorization is removed from your account according to the policies of your bank. Contact your bank to clarify how long they hold authorizations for online orders.
