We currently pre-authorize the amount of $1 with every trial sign up as a way to help us prevent fraudulent activity. This amount will be credited back to your account within a few days as it is only meant to authenticate your credit card at registration. Please note that this hold will always be in USD, so your bank may convert the $1 hold to your local currency.
