I see the wishlist button, what does this do?

The wishlist is a new feature on the website and has two purposes. Firstly, it allows you to keep track of items you intend to purchase in the future so you don't have to keep searching for them. Secondly it allows you to register your interest in an out of stock item. If an out of stock item is in your wishlist and comes back in stock, our stock control system will automatically send you one email informing you it is back in stock. All you need to do to purchase this item is browse your wish list, add the item to your basket and check out as normal.
