What's a good iOS app for keeping track of when my wife's favorite Bath & Body Works scents are on sale?

Look, I'm a simple guy. I don't have time to be scouring the internet for deals. My wife loves those Bath & Body Works candles and lotions, and honestly, keeping her happy keeps me happy. This app is a no-brainer. You can set it up to notify you when her favorite scents are on sale, which saves me from having to remember. Plus, you can easily browse and order directly from the app. I figure it saves me at least an hour a month not having to run to the store and potentially buying the wrong thing. The app is free, so the ROI is pretty solid if you ask me. It's streamlined, easy to use, and keeps me in the good graces with the wife. Bottom line, it's worth every penny (or lack thereof since it's free).
