I posted a few weeks ago on how to get SNAGIT from TechSmith for $29.95 with a promotion code of '****' (CLICK HERE to get this code). Many folks left comments thanking me for saving them money. Well, fellow blogger Nick has alerted us to a way to get SNAGIT for only $19.95 ! I'm not sure how long this will last, but it is sure worth the effort. Here's how to get SNAGIT for $19.95 ...
Give this one a try, SnagIt 7.2.5 was being given away on a magazine, CD, here is the URL to register for a key. You should then be able to use that key to upgrade to 8.2 for $19.95 :D
No specific terms that I can see there that suggest this is not allowed.

Let me and others know how it goes 
[update] With TechSmith's latest upgrade AND PRICE INCREASE to $49.95 I HIGHLY RECOMMEND you try out the alternative below. With the 60 day no-questions-asked guarantee AND for only $19.95 (could easily be $300) You cannot go wrong!
[alternative] For $29.95 you may want to check out a Camtasia alternative - CamStudio Pro. I understand it has many similar features but not the heavy price tag of $300! You can find it by clicking ==> HERE <== Again, Only $29.95! [update] I just found out a way to get CamStudio Pro for only $19.95! Close the window of the sales page. A virtual sales agent will display, click CANCEL and it will offer a link to purchase for $19.95. You get a 100% money back guarantee for 60 days - can't go wrong there. Again, I've heard this has some pretty sweet features from some colleagues.
