They just have the paypal logo. Like other similar sites the paypal accounts had been suspended. They're apparently going to use the whole sale distribution site taodaobao.com. I don't know if that takes paypal, I noticed they also removed all of their flashcarts from the store.
UPDATE: They just posted on their facebook that Paypal is back. I'm guessing they were able to get it back because the removed all flashcarts, knockoff toys, and fake beats headphones from their store.
