Paypal credit card. Prepaid card authorized for online purchases. I dont believe these options will let you choose a reoccurring sub.

or Amazon ( https://www.amazon.com/Star-Wars-Republic-Prepaid-Subscription/dp/B00HWYDM3O ) to buy off Amazon with Paypal you'd need a Paypal credit card anyway.

I'm seeing the 60-day code available, though Amazon says "only 1 in stock" which is hilarious since it's not a physical product

They have a 60... https://www.amazon.com/Star-Wars-Republic-Prepaid-Subscription/dp/B00HWYDM3O/ref=sr_1_2?keywords=swtor+game+time+card+30+days&qid=1577596847&sr=8-2

If i remember correctly, there are no 30 day prepaid cards only 60 and up
