I downloaded bargain bin app which I have to say looks really cool. This app let’s you find apps on sale like some others out there but also let’s you tag apps that you want and allows you to set a price that you’re willing to pay. The coolest part with that is they’ve added push notifications so you will receive a message whenever your apps reach that price. You can also be more generic and get notifications on a broader range as well when they’re are price reductions.
The app is free so check it out!
