If you navigate down to the trophy at the bottom of the interface - it's marked "achievements", you'll notice it opens a box where you can see all the items in the game that you have collected or are progressing towards. You may also notice there is a small blue "i" icon next to each item.

If you use the search bar located on this screen, you can search the name of any product, and click the blue "i" to see how to get it.
