If you have a PayPal account, you can also check the balance that way. You would sign into your PayPal account, click at the top on "add funds" ... and then choose the option about Moneypak. You will then have the opportunity to put your MP info in. Do that, submit, and it'll show you the balance. At this point, hit cancel or return to PayPal account -- that way, you have just checked the balance and not actually loaded it into your account.
