IDW is moving from iVerse-based apps to Comixology-based apps so maybe things are still in flux. All of their Star Trek titles will be published same day as print at the same $3.99 price. They've been dropping the price to $1.99 four weeks after initial release.
Pisses me off that the didn't send a notification through their app alerting readers of the change. That's the whole point of having a notification system. Plus it bothers me that I'll have to keep two different comics apps on my iPad as I have quite a few issues that I bought prior to the switchover.
IDW handled this in a pretty poor fashion.
