Credit card

LWN was the first site I used my credit card on back when I first got a credit card (it took me some time before finally deciding to get one, since local payment methods like boleto bancário mean you only really need a credit card for foreign websites), and I kept renewing it since then. I have no intention of stopping, even though using a credit card to pay on a web site can be a pain (you never know when the bank will randomly decide to reject a payment, requiring you to phone to unblock the card and then retry the payment on the site).
