I figured that one out--you can order only the ones with the "Buy" button that link you to some other website. Yarndex is just a directory of information, not a store it seems.

As far as buying the yarns listed in Yarndex, I recommend you do a search for them on trusted sites like Yahoo!Shopping, BizRate, or Shopzilla. You'll come up with different stores that carry the yarns. Also, try doing a search for the yarn in Ebay - sometimes there are great yarns at great discounts.
