annoying "buy it now" popup

I will uninstall it. It seems that there is nothing new or different than the osx screen saver except that it forces me to make a couple more clicks each time it is activated. The popup ad to "buy it now" is very annoying. Seems that all thses apps are doing this. Oh, and why isnt there a "Remove it now" to click on and there should be an option for this here in the App Store.
