It is possible to buy a subscription with stripe or paypal? I have money in my paypal account, and I'd much rather use it than what I have in my bank account.

Stripe is the system that uses your credit/debit card. But no, unfortunately you have to use it to subscribe. You can always just buy CSC with Paypal instead and buy a GA that way.

Yeah, but that costs more, and I'd like the benefits of getting CSC each month. That's a bit disappointing, but thank you for answering my question. ^^
