After all that, they don't mention Plastic Jungle again in the article at all, so I'm not sure why it's even slipped in there.
Also, are TC taking the Demand Media approach now, and just doing as many articles as it takes until one popular one hits? There's a near identical article posted a couple of weeks ago. (http://techcrunch.com/2010/02/18/cardpool-wants-to-buy-and-s...)
There were also two articles about Cardpool's "reveal the online code before sending physical card" feature (http://techcrunch.com/2010/09/07/gift-card-marketplace-cardp...) (http://techcrunch.com/2010/12/20/cardpool-speeds-up-gift-car...).
It seems if anything, they're making a special effort to make sure Cardpool and Plastic Jungle are mentioned together as much as possible (including the SEO-style URL "gift-card-marketplace-cardpool-plasticjungle" instead of their usual article-relevant URLs).
