I'm guessing that it was an error due to the recent changing of the homepage and appearance of the site. On the Moniker.com homepage all the common extensions are $9.95. From another thread, it looks like 3000 LLL.CC domains were registered this last week. Moniker may have lost ~$20000 due to an error if this is the case. (Possibly more if there were other .cc speculator purchases) The LLL.CC speculators may be disappointed but I think that $9.95 for a LLL.CC may still be quite a good buy.
NNN.CC domains were being bought out anyway and so I don't think those who bought them should be disappointed. It would be nice if the .CC registry did drop their prices.
