I've been using Snagit for years and recently got a notification saying that I can get a "special" upgrade price is $24.95. The regular price is $50.
Upon investigation, the special is available to everyone - even people who have never purchased Snagit before. Version 12 of snagit provides a new license key and no previous key is required during activation.
In other words, anyone can "upgrade" to the new version of Snagit for $25. Bargain!
PicPick is pretty good, and Free.
