RedDeals is the best way to find great deals on the games you want. Do you know reddit? Browse the GameDeals subreddit and add games to you wishlist. You can also add wildcards as: online shop, sagas, publisher, special offers... (anyone said "humble bundle"?). Whenever a sale matching your wishlist is posted to reddit, RedDeals will notify you, giving you the chance to go to the offer, view the post on reddit or dismiss it if you don't find it attractive.

Very useful for keeping track of sales
Works great Has saved me a bunch of money!
Interesting idea, however the app keeps notifying me every other minute so I was forced to uninstall it.
