Why am I charged $1 when I sign up for a free trial?

When you sign up for a free trial, StudyMode authorizes your credit card or PayPal account for the nominal amount of $1 (or similar amount in your currency), to check that the payment method is valid, and so that we can validate the person participating in the promotion.

Don't worry – you won't actually pay this amount. It's possible that you will see it as a Pending transaction on your bank statement for a couple of days, but as soon as your payment method has been authorized, we cancel the charge.
