Products not lined up

Hello,

I am trying to set up a shop page for my affiliate links. I put a few products on the page and they seem to be not lining up in the grid like fashion they are supposed to. I followed the instructions and made sure my settings were how they are supposed to be and included the short code that was suggested. However, the products look like they are practically on top of each other and the images and descriptions are huge. Is there a way to change this to where it is smaller and more evenly spaced?

The page I need help with: [log in to see the link]
