Checkout
From HelpWiki
When you think you have selected all the items that you need, simply go to the top of the store page and click on the button that says checkout. Don't checkout unless you know you have all the items you want selected. When getting items, you won't actually pay for them until you actually check out so make sure you don't forget to. A lot of times you might have selected items and just left without purchasing them and then you have to go back again to redo it. You must checkout in order to get the items you want officially.
