This is permission for a single transaction only, and does not provide authorization for any additional unrelated debits or credits to your account. When you sign the form, you certify that you are an authorized user of this credit card and that you will not dispute the payment with your credit card company; so long as the transaction corresponds to the terms indicated in this form.
