You get absolutely nothing with this

First off, this app is exactly what you use when you open up their website in safari. Second, there is no wish list on this app. Third, you have to sign in every single time you open this app. Fourth, when you click a link to your order tracking number it takes you to the page but (if theres more than one shipment in the order which happens almost every time to me) you have to close the app and sign back in to look at another one.
Just use their website from a computer and you will run into about half the problems the app gives you.
