The app suddenly stopped working, as I couldn't get the deals through at the in-person check out. I tried multiple times, but to no avail... so I gave up, not getting any deals. I also miss the old version of the app, since it showed multiple deals at once that I could pick and choose. This new one only shows one at a time, so I have no choice in which deal to go for. Oh well, so much for that. I ultimately ended up uninstalling the app.
