Why was there a small charge on my credit card?

Upon signing up, a $2 charge is initiated to verify the validity of your credit card. This charge will be promptly voided within one business day. The purpose is to confirm the authenticity of your payment method.

If you update your payment details after your initial signup, there will be an automatic charge of up to $25.00. This charge will be credited to your future payments. If the charge fails, your account will be suspended.
