Mine fell by 50% in the last month or so. I would have assumed that advertising budgets will increase for the holidays. It is also possible that there are a lot more publishers entering the market. There is a supply/demand thing going on here with the available amount of advertising and the available advertising space. $1 per click or even $0.42 per click is still very high. I get about $0.03 - $0.07 per click. I would imagine that your keywords will eventually drop further as more publishers enter your niche.
