Change billing to use Paypal

I’d like to use Paypal instead of the CC billing, how can I do that ? I tried canceling my subscription but then I couldn’t find an option to reactivate it using a Paypal account. Can you please give me directions ?

Wait until your subscription is canceled. Then use the following link: Note that we only have yearly subscriptions with PayPal.

Hmm, too late, I already reactivated my account with the CC billing option. Anyways, I’d prefer to subscribe month after month because I’m not sure if I will use Xert during the outdoor season.
