Redirecting homepage to shop page but still having home available

Hi guys,

If you go to the site: https://paperboyposse.com you will see that you are initially at the home page and then can direct yourself through other pages.

So what i want to do is when you go to https://paperboyposse.com you are initially on the shop page and then you can navigate to the home page if you wish (The homepage is the page which is currently on https://paperboyposse.com and the shop page is at https://paperboyposse.com/shop)

How would i go around doing this?

Thanks

Ash
