The next step is to click-on the PayPal logo for payment. You do not need an existing PayPal account to use their service for a card payment.
If you don't have an existing PayPal account, click-on "Pay with Credit or Debit Card" when you are taken to the PayPal screen. The default country is "United States" (as the forms server is in the US). Be sure to change to "Canada" after you click on the link!
You will need your exact credit card mailing address, along with your 3-digit printed code on the back of your card. If you can't complete the PayPal transaction and just abandon the process, you can re-register at a later date when you have all the required information. We'll see the duplicate entry and fix it!
