Not working. It's 2€ and 1€ in Store as well.
Easy to locate, (re)download, (re)install, and use.
All of the reasons you mention are of very little use. The real benefit comes from not having to manually update anything (or hoping the publisher of the software has implemented their own system for automatic updates).
That said, not worth it to me in most cases since software outside Store is usually better, but it's still a valid point.Last edited by Zkuq - on 05 March 2018
