Hi Flond,

This has been suggested in the past but was denied, If you wish or cannot make a paypal account due to being under the age of 18, you are able to pay using paypal without creating an account.

If you have more questions about this, I would advise contacting the CM Team via either Discord/TS or via the contact us page

Thanks,
