I predict a lot more of that, I have two other catalogs and will drop most of them. With renewal pricing over $10 there is a time to drop domains that have no action.
I remember saying that the price increases will affect renewals and I was only able to speak for myself, looking at the costs I decided to drop over 2000 of them from one catalog alone. These were part of acquisition buys but I renewed most of them until I could see a pattern in the traffic stats. Before I would keep the ones I liked without traffic but now I am much more inclined to drop them.
Seeing the increase in drops makes me believe I was correct in my assumption. All in all the price increases may actually be dropping CIRA's income instead of increasing it.
