Out of curiosity, why do you care if CCC uses affiliate links? Not trying to troll, just genuinely curious. I figure if CCC gets a bit of a kickback on something that's fair for me using their site as a means of keeping it going.
I'd understand if the grand parent poster refused to use price alerts at all, maybe in order to avoid unnecessary purchases, but GP argued that a different service is better because it doesn't use affiliate links, which seems rather strange to me. After all you get an alert for a product you chose at a specific price you defined. The use of affiliate links doesn't change anything in this arrangement.
