Hi there! You can choose to pay via Visa without needing to create a Paypal account.
Just select 'Paypal', then select to 'pay with Credit or Debit', fill out your info, then at the bottom of the screen when it asks if you want to create a Paypal account, select 'no thanks.'
It goes through Paypal for security purposes, but there is no need to actually create or have a Paypal account.
