Ari gave me a plugin and code to make my store page show

Hi, Ari gave me a plugin and code to make my store page show as my landing page

the store shows the products grid as I desired, but below the image grids is all the website information for miles

http://www.1stBookStop.com

can you advise how this can be changed so nothing shows beneath the images?

I added this code to a separate new page, then to the "store" page
however, same problem occurred once made a static page

please advise

thankyou

Glenn
