Paid account extention with Paypal?

[shirokuro]

Hi, guys.
My paid-time is soon expiring; I'd love to renew it, but it's not that simple atm - my credit card has enough payments already. I do faintly remember someone saying they can buy it for others when the buyer pays for it through Paypal. I can't seem to find that post/thread, though...
So, do you know anything about it or is someone willing to do something like that? Either goes.
