You'll probably come to using this app a lot. It's nicer to look at than their website, the stuff you buy is usually pretty good, it's very convenient, stuff arrives well and refunding stuff is easy. The only real bad thing about the app is that it can be hard to find certain sections, eg the "Message Centre". Just remember you are buying from Amazon at the end of every purchase - the technical side isn't great, like sometimes receipts don't add up individual items to exactly the right amount.
