All shops require a wire transfer/services like web money and alipay.
Is there a shop that you can buy it from with a credit card?

Better question would be, where can you buy without CC ?
Anyway, my last buying of GW was from Chinese dealer "Eachmall" it took 3 weeks and its considered very fast with them. I paid directly with debit card there. You have also Yeahgeek and you can pay directly with credit card ( but only Visa, keep that in mind). They are also Chinese store like Eachmall, but they ship very fast, and nobody had bad experience with them.
So Eachmall or Yeahgeek, I don't know any other that would better answer on your question.
