I use PayPal to process online payments because it's quick and easy.
You can pay using your Credit or Debit card as you do normally with any online purchase.
Check the instructions below.
STEP 1 - On checkout page
Write your email address in the field above the yellow Paypal button...
If you are already registered because you have purchased any product (even free) the system will recognize your email and you will be invited to Sign In...
Sign in with your email and your password and press the "Sign In" button. After that you will go the Paypal payment.
If this is the first time you purchase you simply press on the yellow Paypal button
STEP 2 - On PayPal popup
Click on the grey button “Pay with a card”.
NOTE: If you have a PayPal account, insert your email to your account and proceed with the blue button "Next".
Get on the “Paypal Guest Checkout and insert your credit card and other requested info
When you have inserted all the info, press the blue button “Continue” at the bottom.
If you want you can check the “Save my payment info and create a Paypal account” (optional).
