Checking the Subscription Type

In order to check how you purchased your current subcription, you will need to go to the My account page and check the "Active Subscriptions" section at the top of the page.
If the name of your active subscription contains the phrase "- PayPal", then you have purchased your current subscription using the PayPal system. If it contains the phrase "- Credit Card", it means that you have purchased your current subscription with your credit card.
