Mostly things look the same for you. The areas we have changed are the product listings themselves, which are now displayed as simplified catalogues without the bells and whistles of old, as you'll see here in our New Releases catalogue, for example. Simplifying things in this way enables us to spend more time adding far more products (and therefore more choice) more quickly.
We hope that you find navigating around the new format nice and easy and that you come to love the simplicity as we do.
If you need any help at all, just shout up.
