SE's billing system is so broken that it accept me purchasing a time card, register my credit card for automated renewal but give me the error 401 if I try to buy a server transfer. My wife, using the same CC, managed to buy all those things for her and I can't buy the server transfer. My bank says there are no problem at all with my card and SE have the guts to claim it's not on their end. They might think we're all idiots.
