If you are making a one time/stand alone purchase, yes you can use your PayPal account as your payment method.
If you are joining our membership, we are not able to use PayPal as your payment method.
PayPal does not supply Saranghae with your payment details, so we do not have a payment method on file to charge your next bundle.
We apologize for this inconvenience.
If you purchase a membership and are able to check out using your PayPal account, please contact our customer care team to have your payment method updated.
