CamelCamelCamel has not went anywhere. But they also don't serve affiliate links as far as I can tell, so their revenue model (if they have one) is not dependent on an affiliate relationship.
CCC does serve affiliate links. If you go to any product page on CCC and click the "Buy" button, you'll end up at Amazon and the URL will have the "tag=camelproducts-20" for their affiliate code in the URL. I'm sure every Amazon-bound link on their website or browser plug-in will do the same.
