Back Button in Desktop Shop

Blizzard shop looks great and I like the layout, but why isn’t there a back button? If I’m looking at a subsection like “Mounts” and decide I don’t want to purchase, it looks like the only option I have for navigation is the top menu. Which takes me back to Games > Whatever game I’m looking at OR the Home button, started the process entirely over.

If there is an option to get back to the previous section I was looking at (ie. all mounts, or all new items, etc) I must be missing it.

I don’t feel like this has to be ugly or take away from the page aesthetics… he’s a sloppy and quick mock up: https://i.imgur.com/D61sfXz.jpeg
