Alibaba is a whole sale website. Generally sellers there are not interested in selling directly to the consumer in smaller quantities. The only way to get small orders from most sellers is to pretend to be a reseller wanting to source a sample. If that's too unethical for you go to eBay and pay ridiculous prices.
Or if enough people here are interested in these cards maybe we can get a group buy going but that would mean one person would have to put in the order for all the cards because I'm pretty sure Biwin wants to avoid sending out single or two cards to 30 different people.
