@Don, they are really not rare at all here in Taiwan. It's interesting, all playing card companies have their official dealers here, every time a new deck releases, few days later we can get it with almost the same price but the shipping fee makes a big difference. The most interesting part is "there are not so many collectors in Taiwan", hence supply is always more than demand. When a deck is OOP and the price increases with time on eBay or other areas in the world, it is still on sale for the original price here. There are too many examples, especially those custom decks such as S&M. Finally they would be sold out, but it takes much longer time than that in other areas.
As for the standard Bikes, there are 6 Costco's here and standard Bikes are really cheap decks. Even lazy people like me can get Bikes from online stores or auctions with the same average price. (In fact, the Ohio made 2006-2008 Bikes are still available here, but they are slightly more expensive of course, about $2 USD)
